Rolle (replaced with Foxworth)
Scott (replaced with Gooden/Ellerbe/McClain)
Leonhard (replaced with Landry)
Bannan (he started due to Gregg's injury, and now Gregg is back)
If anything I would say we've gotten faster. Landry and Leonhard might be a lateral move in terms of speed, but the other three guys we're definitely slower than who they were replaced with. We also only have 3 guys over the age of 30 on defense who start (Lewis, Reed, and Gregg). It's not like we're an old team.
I hate making excuses for players (and ours have had more than their fair share of terrible plays this year), but it's looking like a lot of our defensive problems are coming from the scheme that is being used. We are in no way a 4-3 base team, yet Mattison insists on trying to rush four on most downs. Anybody that has seen us pla can tell you our pass-rush is absolutely terrible. This leads to coverage problems, etc.
FIRE GREG MATTISON!
