I think Hugh Douglas is past it - and that our DL right now has all the depth it needs with Ritzmann on the PS in case of injuries.
Our DL has loads of upside. Shobel is a given, Kelsay keeps improving, Denney is a good backup, Adams is All-Pro, Anderson shows improvement and effort, Edwards has starting experience and can rush the passer, Sape is the Sapemeister, and Bannan is mr versatile.
