I'm not a big fan of how Wommack's defense works either but I can tell you what makes most systems look good, and that's better players. We've had a drop off in LB play (and talent) that hasn't helped the scheme. Jefferson has definitely improved but he's somewhat small and Lawson is going to miss four to five gaps a game on run fits, you can bank on it. I think if we can get more talent at the LB position and get a little bigger at the defensive tackle position, we'd see a lot less of the busted run plays.
