Who is going to be the 2011 NFL Draft's Vernon Gholston?

Many people have mentioned Gholston’s name when they voice reservations about drafting Quinn. People seem to think that since he played DE and had to switch to 3-4 OLB that the switch was the reason he failed. But that is waaaaaaay to simplistic.
VG was a high 1st round draft pick because of his ability to get to the QB in college and because he was a rare physical specimen. His combine numbers were mind-boggling:
6’ 3" 258 lbs. Bench – 37reps Vertical – 41" Broad – 10’ 5" 40 yard – 4.58
His last(Jr) at OSU he had 14 sacks and 15.5 TFL. And even though he did play DE his last year, he had played OLB his Fr. year and played with both his hand in the ground AND standing up as a redshirt Soph even dropping into coverage occasionally. This should have been a no-brainer slam dunk Pro Bowl player.
But he gets to the NFL and fails, not because he couldn’t play LB. He failed because he couldn’t get to the QB, registering ZERO sacks in his 3 years covering 45 games and 5 starts. Just to put that in perspective, since 2008 there have been 3401 sacks by 649 players who recorded at least 1/2 sack and VG had NONE. How was this possible?
Well, if you go back you find that VG had never even picked up a football until his sophmore year in HS and although he was tried at LB it is written in his H.S. combine report, and I quote, “As a sophmore at Cass Tech VG was first tried at LB but was OVERWHELMED by the plays he needed to know to play the position” He played Offensive Guard, not even Tackle, until his senior year where he is moved to defense. So he plays one year of HS defense and 25 starts of college defense and becomes the #6 pick in the draft. So the risk was there because of his lack of experience before he was asked to make the switch back to LB.
But there is more and this is where you have to go to the tape. When you look at him, there is now way you would imagine a 4.58 out of this guy. His speed just doesn’t translate in pads. But something I noticed is even more important, I think. When you watch the tape you see that he lines up all over the field, sometimes over LT sometimes behind the DT’s in the 0 gap, but sometimes over RT. I mean, I understand it, you are trying to get your best player his most advantageous matchup, but when evaluating such a player, how much credit should he get and how much should go to the scheme? Not to mention, when you are lining up over RT you are lining up vs a player who is probably not making it to the next level(most RT’s in the NFL played LT in college). Of the 21-1/2 sacks he had in college, I saw tape of 19 of them: 3 sacks over LT(although he did beat Jake Long once) , 1 sack over center and 15 sacks over RT. So most of his produciton came vs the inferior Tackle of the teams he was playing against. This is why I always feel looking at the tape and looking at the matchups is the most important thing when evaluating a player.
There were other questions about Gholston(lack of passion/taking plays off; lack of pass-rushing moves) not the least of which was that his game was soft and relied too much on speed, but the simple fact that the Jets were taking a reasonably inexperienced player and asking him to not only switch positions but ALSO to switch sides, to a side he is less productive at(playing Pace’s spot over LT), it is not totally surprising when that player does not live up to his potential. To me, VG’s failure had much more to do with how talented a football player he actually was then switching from DE to OLB. He was a workout warrior who played in a defense built for him to succeed in.
Comparing Quinn, someone who started in youth ball, was getting visits from major college’s after his SOPHMORE year in HS(while VG was in his first year of organized ball playing Guard), someone who started 23 games even though he only played two seasons at UNC and someone who always lined up over the opposing teams best blocker at LT(even in HS) is just not a fair comparison.
