Last years front 7 was much different than this years. Star, Shaq, Jordan Phillips and Lorenzo are gone. Across the board their replacements are not playing better, the case can easily be made that they are playing worse.
Milano and Edmunds are both playing injured and they are not having good seasons compared to last year. We have had injuries at corner that have taken us deep into the depth chart and to using practice squad players. Harrison Phillips is still recovering from ACL.
McD and Frazier did not suddenly become stupid - last year our players we were healthier and better.
Additionally, defenses across the league are worse. Lots of theories as to why.
Fixing the front 7 has to be Beanes top priority. He will do that by adding better players, not new plays.
