NJAzrael71 Icon : (22 April 2015 - 09:17 AM) Rivers is likely going to Tennessee. Would LOVE to have him here but we likely won't make the trade. I'd easily give this year and next year
NJAzrael71 Icon : (22 April 2015 - 09:17 AM) 's first rounder for him
azjetfan Icon : (22 April 2015 - 11:03 AM) IMO that's a steep price. I would swap this years first and a conditional 1st next year. Assuming we make the AFC Championship. That would be a 28-32nd pick. Otherwise a second.
MikeGangGree... Icon : (22 April 2015 - 01:07 PM) Yes 2 1st is a lot
Jetsfan0099 Icon : (22 April 2015 - 01:10 PM) draft is next week, pumped
Chadforpresi... Icon : (22 April 2015 - 03:02 PM) What are thoughts on getting a RB in round 1? McShay's newest mock has us taking Gurley at 6. I don't think we should take him that high, but if we trade down and he's available I'd love to snag him, ACL and all. He's got an unreal skill set that, once healthy, will translate readily to the NFL. We're not getting a QB this year without paying a king's ransom, and unless we pay a ransom for a top guy I say ignore QB. I don't want us to take a Hundley or Petty type in the 2nd or 3rd round when we need other pieces (edge rush, OL)
azjetfan Icon : (22 April 2015 - 03:09 PM) We can probably get Gordon in the second. I would pass at 6. If QB is not available a pass rusher will be. Our biggest needs are QB Pass rusher and Oline.
Jetsfan115 Icon : (22 April 2015 - 03:34 PM) any thourghts on shane ray? i see a lot of mocks have us drafting him
Jetsfan115 Icon : (22 April 2015 - 04:35 PM) last one i seen had us taking cooper, a RB, and hundley for our 1st 3 picks. not thrilled about that
Chadforpresi... Icon : (22 April 2015 - 04:38 PM) I don't like Gordon much. Not much of a receiver or blocker, ball security issues, tries to bounce outside too much, stuffed frequently. Gurley is in a league of his own
Chadforpresi... Icon : (22 April 2015 - 04:39 PM) Ray is pretty highly regarded. I'm betting he, Dupree, and Gregory will be our best options as well as edge rushers at 6, but I think that's too high for any of them
Chadforpresi... Icon : (22 April 2015 - 04:43 PM) Personally love Cooper, I know WR isn't our biggest need but he may be the most NFL ready guy in the Draft. If we stick to the 6th pick and Fowler, Beasley, and Mariota are gone, Cooper is the guy to get. I'd even take him over Beasley
Jetsfan115 Icon : (22 April 2015 - 05:45 PM) i don't mind cooper. decker isn't number 1 IMO and marshall is expensive and getting old
Jetsfan115 Icon : (22 April 2015 - 05:45 PM) and we never draft a WR high
Jetsfan115 Icon : (22 April 2015 - 05:45 PM) but o-line and QB are huge needs. i wouldn't take o-line 6th overall, but i think our 2nd or 3rd should be o-line
Jetsfan115 Icon : (22 April 2015 - 05:46 PM) we need an OLB as well. if we don't land a QB i'd like to see OLB adn O-line with 2 of our top 3 picks
Chadforpresi... Icon : (22 April 2015 - 08:16 PM) I agree on Deck, not a true #1 and he's had a checkered history with injuries. Marshall has 2, maybe 3 productive years left, which is why Cooper is an option
Chadforpresi... Icon : (22 April 2015 - 08:17 PM) And I agree with you on edge rusher & OL being bigger needs, but there really isn't a lineman I'd take at 6
Chadforpresi... Icon : (22 April 2015 - 08:19 PM) So the way I see it, assuming Winston and Mariota are taken when we're at 6, that Fowler and Cooper are our best choices, and I'd be stunned if Fowler drops. I wouldn't be surprised (or upset) if we land Cooper
NJAzrael71 Icon : (22 April 2015 - 08:47 PM) Apparently Tennessee wanted both of Cleveland's #1's and their 2nd rounder to move up to the #2 spot to get Mariota. Still think two 1st rounders are too much for Rivers? He makes us instant contenders and if we make a deep playoff run, it would really be this year's 1st and what equates to basically a 2nd rounder next year.
If not, get Cooper in the 1st and then grab Hundley in the 2nd and O-line in the 3rd.
Jetsfan0099 Icon : (22 April 2015 - 10:05 PM) I wouldn't be upset with Cooper, hes a stud
Jetsfan0099 Icon : (22 April 2015 - 10:06 PM) Not sure about Ray. Dupree is rising on the draft boards, ridiculously athletic for his size
Jetsfan0099 Icon : (22 April 2015 - 10:07 PM) Dupree is 6'4 270 and has a amazing get off and runs a 4.5
Jetsfan0099 Icon : (22 April 2015 - 10:09 PM) Problem is he doesn't have big sack numbers in college, I rather draft a productive guy high
Jetsfan0099 Icon : (22 April 2015 - 10:09 PM) Vic Beasley is insanely athletic as well and was hugely productive in college, good bet is that Beasley will be a 10+ sack guy in the NFL
NJAzrael71 Icon : (22 April 2015 - 10:12 PM) Beasley should be a stud but he gets caught up hand fighting if he doesn't beat his guy quickly. He'll likely end up as an OLB but we'll see
Jetsfan0099 Icon : (22 April 2015 - 10:15 PM) He'd be a good fit in our defense, because we could use that speed guy on the outside
Chadforpresi... Icon : (23 April 2015 - 06:27 AM) I'd love Rivers, but we should be able to get him without paying 2 first rounders
Chadforpresi... Icon : (23 April 2015 - 06:29 AM) Lot of buzz about Dupree going top 10, most mocks I see have us getting either Ray or Dupree at 6. I prefer Dupree, like you said insane athlete for his size
Chadforpresi... Icon : (23 April 2015 - 06:30 AM) I like Beasley as well but I have a strong feeling Washington will snag him. But he is a small dude, it'd be nice if he'd add some bulk (in Clemson reportedly played around 230)
Chaos Icon : (23 April 2015 - 10:11 AM) @ArifHasanNFL

.@LanceZierlein says on http://sports790.com that Shane Ray will need surgery on foot, 5 months recovery. "Could drop out of first"
Chaos Icon : (23 April 2015 - 10:14 AM) this should change up the top 10
Chadforpresi... Icon : (23 April 2015 - 12:16 PM) Damn that's big. If he drops out of round 1 that could be a massive bargain for whoever gets him round 2. Dupree now looks more like the edge rusher we'd get at 6
MikeGangGree... Icon : (24 April 2015 - 09:40 PM) TEH RANGERS
santana Icon : (24 April 2015 - 11:32 PM) TEH WIZ
Jetsman05 Icon : (Yesterday, 06:57 AM) Teh Suarez
Jetsman05 Icon : (Yesterday, 06:58 AM) Vic Beasley is all speed. No moves, no power. Straight up the field. Could have some big games, then nothing in the next
Jetsman05 Icon : (Yesterday, 06:59 AM) If we don't get Mariota, we should be looking at Schreff or trading down, IMO.
Jetsman05 Icon : (Yesterday, 06:59 AM) A lot of good edge rushers in this draft... I wouldn't want to take Dupree that high.
Jetsman05 Icon : (Yesterday, 07:00 AM) Until next time fellas!
azjetfan Icon : (Yesterday, 01:19 PM) Helloooooooooo
azjetfan Icon : (Yesterday, 01:19 PM) Bueller
Jetsfan0099 Icon : (Yesterday, 01:33 PM) Manish says the Jets should trade down and draft Andrus Peat round 1

The University of Otago

The multi-disciplinary study showed that people who started smoking cannabis as teenagers may suffer from IQ decline when they're in their thirties.

Persistent cannabis users who started using the drug before age 18 show an average IQ decline of 8 points and other signs of impaired mental functioning by age 38, according to world-first research emerging from the University of Otago’s long-running Dunedin Multidisciplinary Study.

The Study has followed the progress of 1000 Dunedin-born people since their birth in 1972/73 and is one of the most detailed studies of human health and development ever undertaken. The latest findings are newly published in a paper appearing in the US journal PNAS Plus co-authored by researchers from Otago, Duke University and King’s College London.

Below is a fact sheet of the study produced by the researchers.

The findings:

We studied the association between persistent cannabis use and IQ decline and asked whether IQ decline was concentrated among adolescent-onset cannabis users. Findings come from the Dunedin Multidisciplinary Health and Development Study. The study has followed a group of 1,037 children, who were born in 1972-73 in Dunedin, New Zealand, from birth to age 38 years, with 96% of the sample taking part at age 38. IQ was tested at age 13, before cannabis use, and again at age 38, after some study members had used cannabis for many years.

We found that:

1. Adolescent-onset cannabis users, but not adult-onset cannabis users, showed marked IQ decline from childhood to adulthood. For example, individuals who started using cannabis in adolescence and used it for years thereafter showed an average 8-point IQ decline.
2. Quitting or reducing cannabis use did not appear to fully restore intellectual functioning among adolescent-onset former persistent cannabis users.
3. IQ decline could not be explained by alcohol or other drug use or by reduced years of education among persistent cannabis users.
4. Third-party informants (e.g., friends, relatives) reported noticing more attention and memory problems in everyday life among persistent cannabis users (e.g, losing focus when they should be paying attention, forgetting to do errands, return calls, pay bills).
Why are these findings important?

The importance of “before and after” IQ testing. Previous studies have suggested that adolescents may be particularly vulnerable to the effects of cannabis on IQ. However, until now, research had not been able to rule out the possibility that poorer IQ test performance among adolescent-onset cannabis users predates cannabis-use initiation. We showed that regardless of their initial (pre-cannabis) test performance, adolescent-onset cannabis users performed worse than non-users and adult-onset cannabis users later when they were tested in adulthood.

The findings are consistent with speculation that cannabis use in adolescence, when the brain is undergoing critical development, may have neurotoxic effects.

What is the size of the IQ decline? The extent of IQ decline among adolescent-onset persistent cannabis users (approximately 8 points) is non-trivial. For example, an average person has an IQ of 100, placing them in the 50th percentile for intelligence compared to their same-age peers. If this average person loses 8 IQ points, they drop from the 50th to the 29th percentile for intelligence.

Why is an 8-point decline in IQ significant? Research has shown that IQ is a strong determinant of a person’s access to a college education, their lifelong total income, their access to a good job, their performance on the job, their tendency to develop heart disease, Alzheimer’s disease, and even early death. Individuals who lose 8 points in their teens and twenties may be disadvantaged, relative to their same-age peers, in most of the important aspects of life and for years to come.

How many people does this affect? Only approximately 5% of the 1,037 individuals born in one year in Dunedin became ‘adolescent-onset’ cannabis users. Thus, any effect of cannabis on the brain is confined to a relatively small segment of the population. Nonetheless, findings are concerning given that fewer adolescents today believe that cannabis use presents a serious health risk.

How we measured cannabis use:

We measured cannabis use in two ways: cannabis dependence and regular cannabis use. Persistence of cannabis dependence was defined as the total number of study waves out of five (ages 18, 21, 26, 32, and 38) at which a study member met criteria for cannabis dependence. Study members were grouped according to their number of dependence diagnoses: (a) those who never used cannabis at any study wave and thus could not have become dependent; (b) those who used cannabis at least once at one or more study waves but never diagnosed; © those who diagnosed at one wave; (d) those who diagnosed at two waves; and (e) those who diagnosed at three or more waves.

Cannabis dependence is a substance-use disorder as defined in the Diagnostic and Statistical Manual of the American Psychiatric Association (known as DSM-IV). The purpose of the DSM-IV diagnosis is to predict a patient’s future prognosis, and to identify which patients are most in need of scarce treatment resources. A diagnosis of cannabis dependence generally reflects an individual’s continued use of cannabis despite experiencing significant health, social, and/or legal problems related to cannabis use.

Persistence of regular cannabis use. Because some people use cannabis on a regular basis but never develop problems, we also examined neuropsychological decline as a function of persistent regular cannabis use. This was defined as the total number of study waves out of five at which a study member reported using cannabis four or more days per week (the majority of days in a week). Study members were grouped as those who: (a) never used cannabis; (b) used but never regularly; © used regularly at one wave; (d) used regularly at two waves; and (e) used regularly at three or more waves.

Results were similar for persistent cannabis dependence and persistent regular cannabis use.

How we defined adolescent-onset cannabis use:

We defined adolescent-onset cannabis in two ways: 1) cannabis dependence before age 18 or 2) weekly cannabis use before age 18. Results were similar across both definitions.
How we measured IQ

We assessed intelligence in childhood (ages 7, 9, 11, and 13) and again in adulthood at age 38 using standard tests for the field.
How we measured everyday life cognitive functioning

Study members nominated people "who knew them well." These informants were mailed questionnaires and asked to complete a checklist, including whether the study member had problems with their attention (e.g., “can’t concentrate, mind wanders) and memory (e.g., forgets to do errands, return calls, pay bills) over the past year at age 38.
What additional research is needed?

Our findings suggest that cannabis use before age 18 predicts impaired mental functioning. However, we do not know how much cannabis needs to be consumed and across what ages before impairment occurs. Given that the brain undergoes dynamic changes from the onset of puberty through early adulthood, this developmental period should be the focus of future research on the age(s) at which harm occurs.

Additional research is needed to determine whether cannabis-related IQ decline is reversible. We found that adolescent-onset cannabis users performed worse in adulthood than in childhood even after they had quit or reduced their use for a year or more as adults. This suggests that quitting or reducing use does not fully restore functioning among adolescent-onset cannabis users in this time, but longer-term follow-up is needed.

Findings are limited to a cohort of individuals born in Dunedin, New Zealand in the 1970s. Additional research is needed to determine if similar effects are seen in other countries and in today’s teenagers.
