First of all, I want to say that I am a Jason Worilds fan. I think he catches more criticism than he deserves and he shows a lot of potential. That said, OLB is one of the most important pieces of our defense and if James Harrison leaves we have to consider a pass rusher with our first pick.
Walter Football right now has Jarvis Jones falling to us at 17. If that happens it is because of borderline criminal negligence by the first 16 front offices. Jones was probably the second best defender in college football this year, behind only the Man-Beast and probable 2014 #1 pick JD Clowney. His stats are absolutely ridiculous and watching him play is reminiscent of James Harrison in his prime. Adding a piece like Jones will get both him and Woodley into 1 on 1 situations enough to make our sack and turnover numbers look like they did a few years ago. I know there are medical concerns, but Georgia's staff has cleared him and he has spent the past two seasons making SEC O-lines and QBs look silly. If he is available at 17 and his physical doesn't completely bar him from playing, Jarvis Jones MUST be our selection. It might even be worth considering trading up to get him, if he's still there at 8-12ish.
Other than Jones, Barkevious Mingo, Ezikiel Ansah,and Dion Jordan are the other three guys that will probably go in the top 20 that I would be happy taking at 17 in that order (Moore and Werner will almost definitely be gone by the time we pick and they're more 4-3 players anyway.) All three are elite athletes who haven't quite dialed in the technique required to play OLB in the NFL, but with Dick Lebeau's tutelage, they could be future stars.
The other Florida State defensive ends: As far as later round prospects go, I think that Tank Caradine and Brandon Jenkins from FSU are both intriguing possibilities. Jenkins was viewed as a high round pick and the best DE on the team before he got injured and Werner picked up the slack. Caradine came in to replace Jenkins and perform impressively then proceeded to also suffer a season ending injury. Assuming either or both are healthy, these are two tweener type players who could come in and challenge Worilds for a starting role.
My dream scenario for the first two rounds relies on other teams making the sorts of poor decisions that you see on draft day too often. Front offices will have to outsmart themselves and pass on a monster like Jones because of a less than stellar combine and past injuries. Colbert has to do what he does and capitalize on those mistakes, grabbing Jones in round 1. Next, another elite linebacker with bizarre off the field issues and less than ideal athleticism could possibly slip as low as the mid second round. If T'eo is available when we take our second pick, he would be another immediate starter and future pro-bowler. I know a scenario like this is unrealistic and it relies on other teams making fantastically bad decisions, but imagine a line backing corps with the disruptive play making of Jarvis Jones and the sure tackling and ball hawking of T'eo.
