Out of this list of DC's, it's Marvin Lewis and it's not close:
-I don't care if he hasn't been a DC in years, ever stop was a successful one. It's not like he's been sitting home, he's been apart of the game.
-Many forget that the Bengals don't have a scouting department, it was Lewis picking the players. He built that defense from the ground up.
-He has experience in coaching all schemes.
-Say what you want about the Bengals, playoff failures. Carson Palmer would of won several if the Steelers didn't take that dirty low hit on his knee.
-Quinn/Whitt both just got fired cause Atlanta's Defense was as bad as the Cowboys. It makes zero sense to hire either one of them. Yes, Quinn has a Super Bowl ring, but he never built that defense, he took over when the defense was already built for success.
-George Edwards worked under Marvin Lewis and Mike Zimmer. His main responsibility was helping with the game plan, not making the defensive in game calls. He was here last year and was apart of the problem as the linebacker unit was among the least productive on the entire team.
