I don't want Zimmer.
His defenses continually fizzle down the stretch (remember all of those late December collapses?). In 2004, in the 4-3 scheme, we had one of the worst defenses in Cowboys history, under Zimmer. In 2006 in the 2nd season in the 3-4, the defense completely collapsed because Zimmer could not figure out how to defend running backs, even fullbacks (see Mike Karney) catching passes out of the backfield. To me, that was just as egregious as anything. In the final game of the regular season against Detroit, Parcells took the defensive playcalling duties back because they were so bad. Then he left mainly because he knew he wasn't going to be asked back, even if Parcells stayed.
He then went to Atlanta and stunk there.
The only time his defenses became consistently good was not until he went to the Bengals with Marvin Lewis, one of the best D-Coordinators in the past 20 years, as his head coach. Even still, here's a look at the Cincy defensive rankings under Zimmer according to FootballOutsiders.com:
2008: 15th
2009: 13th
2010: 17th
2011: 17th
2012: 10th
2013: 5th
They've been steady, but nothing I would exactly write home about outside of this season.
I remember Sean Payton struggling so bad in New York that Jim Fassel took away his play calling duties and the Giants offense surging afterward. Then Payton finally took over playcalling duties in 2005 for the Cowboys and I was quite unimpressed.
Even in 2006, I felt Payton's play calling with the Saints was a bit of luck and opposing teams struggling to prepare for Payton, Brees and Bush (and Colston). A couple of years afterward, Saints fans were calling for Payton's head. But, he started to identify his weaknesses and finally put together a solid defense and then won the Super Bowl and it is obvious that he has seen what Parcells would rip into him for throwing the ball way too much (as we saw in the Philly game, they marched right down using the running game and closed out the game).
Perhaps Zimmer is finally learning and could be the guy, but I have to really question it and his track record isn't bad, but it is far from stellar.
