On paper it looks like an improvement, but... The dline gets beat up in 3-4 & I am not convinced Payne and Walker will be around for 16 games. Coleman seems to be doing OK & will be improvement but it is a new position. I would play Eric Brown mid range to support Robinson and stop a dink type pass when outside backer rushes QB. Shade Coleman closer to Dunte side of field as Glenn should handle his side.
The big key to this defense is linebackers. I still seen no reason to think we will get more than 3 from Peek or Babin. Boy, I hope I am wrong! Keep in mind that in 2002 a lot of teams underestimated H town and I do not think that will happen this season.
