Tj... Ramble on!!! I didn't say he made a HUGE impact, just that he was good vs the run. Julius Peppers may be the only DE right now dominant against the run. Rolle did predominantly cover the opposing #1 WR under Williams. Schwartz initiated the change upon arrival. Due to teams like the Patriots success with zone D's at the time, Schwartz started converting the Titans D to a zone D...and that was WITH guys like Rolle. He is simply more of a zone guy and is trying to 'borrow' from the best DC's in the game. Unfortunately he doesn't understand how and when to use these schemes which is why they don't work for us. The more he has changed over the years, the worse the D has gotten. Of course that also has to do with losing talent and the culture Williams created. Schwartz is not a matchup guy...period.
