Wimbley isn't a bad player at all -- in fact, he's picked up 42.5 sacks in six years, which is pretty impressive. However, he's never played exclusively as a 4-3 defensive end, and as our own esteemed Tom Gower noted on his Total Titans blog, four of his seven sacks in 2011 came against woefully overmatched Chargers backup tackle Brandyn Dombrowski.
If the pass rush is going to be any better in 2012 than it was in 2011 the Titans are going to need to do some different things than they did last season. Lining up with basically the same guys and expecting a different result is crazy.
My thought is that Jerry Gray has something up his sleeve. We will probably see multiple looks this season with guys like Akeem Ayers, Kamerion Wimbley and Zach Brown lining up in different positions.
