Count me as another shocked reader to see Leonard go as well. Granted, I get it that its a numbers game, but, I was just shocked to see him go after last season. The move makes sense though. With Scott, Harrison and Spiller - Leonard would just be taking up a roster spot. I don't think it would be likely that he would even see the field much.
I'm looking forward to you defensive line rotation. You really have some big guys that you can put up there. I think, at the very least, you will see a big improvement in your play against the rush.
McDonald may have impressed in the preseason, but I like that you are keeping him in the slot role. He has so much speed and the routes for the slot receiver in the Saints playbook are really probably a better fit. His athleticism and speed should help him get seperation from the CPU corner. You have a nice receiving trio going into the season. I think its possible that all three of them could have between 50-60 catches each if the ball is spread out.
