Initially I had Vilma as a top 2-3 LB, but with the changes from 4-3, to a hybrid 3-4 i'm more weary on him, this also applies to DL like Jason taylor, who could also play OLB in the phins 3-4 sheme, I know this affects many teams, what do you guys think?
There are at least three variations of the 3-4 scheme in the league right now.The Belichick version (hybrid, multiple looks from a base 3-4) run by NE, CLE, and the NYJ. A mostly balanced version of the 3-4 front run in different ways by SD, DAL, and PIT (who throws a bunch of zone blitz looks into the mix also). And Saban's version of the 3-4, which is much like Belichick's but uses a lot of one-gap looks on the line.
For the most part, the DE in the 3-4 will have a hard time hitting the boxscore. They're expected to hold blockers (often two) instead of attack and are rarely quick/strong enough to defeat both blockers in run support or pass rush. There are exceptions of course, but very few. Saban's scheme is kind of a Jeckyl-Hyde situation on the line. Taylor isn't exactly a rush linebacker, but he'll very rarely have two gap end responsibility, if at all, so he retains his value. There is a small chance that he'll continue to have increased coverage responsibilities and be re-classified as a LB, but I think his pass rush value is too high to see that happen soon.
The OLB role in the 3-4 is entirely dependent on responsibility and your scoring system. On one hand, you're going to have guys like Demarcus Ware and Manny Lawson who are likely to struggle in run support and serve a rush LB role. They'll have value only in sack heavy scoring systems. On the other hand, you'll have guys like Bobby Carpenter or Willie McGinest who will probably make enough plays in run support to be on the radar of all leagues, but may not have an impact in any. Then you've got the Shawne Merrimans of the world, who may be the rare OLB who makes enough plays in run support and are terrors in pass rush to be valuable in all leagues.
The ILB role is pretty much the same in all versions of the 3-4. You're looking for the same guys you are in the 4-3 (strong, instinctive tacklers), but you'll need to pay attention to the surrounding personnel a bit more. First, you'll need to identify the LILB - they're aligned to the strong side of the formation most often in balanced fronts (Edwards, Farrior) and have MLB responsibilities (A. Davis) in unbalanced (dedicated rush LB) fronts. To become a stud in a 3-4, the ILB needs to either have a stud NT (and solid DE) to keep the bigger offensive lineman off of him or have elite strength and quickness to leverage himself against or elude blocks. Vilma has the skill set to succeed in the hybrid 3-4, but he's going to be limited somewhat by the lack of a true NT on the current Jet roster. Dewayne Robertson may have the size, but he's more of a one-gap penetrator than a plugging man-mountain type. How well Vilma can overcome that remains to be seen, but, for now, I'm still in his corner.
