I maintain the same position in regards to QBs as always. Regardless of circumstances, surrounding talent, coaching, etc...eventually you have to perform. EJ did not. The league is littered with QBs who if everything around them is perfect can be really good. The great ones make everything around them good.
Seriously, you could have had Adam Gase as the coach of Peyton Manning and it wouldn't matter. Manning would have been great.
