I would expect much of the same from Kamerion Wimbley. Sure, he isn't Mario Williams, but they also didn't give him nearly as much money as they would have had to give to Super Mario. The other plus Wimbley has over Williams is that he does not have the history of missing games because of injuries.
The Titans desperately needed to improve their pass rush. There is no way to know how many sacks Wimbley will have in 2012, but there is no doubt that he improves the pass rush.
