It's his actions that will ether prove he is a great coach, or Drew really was the brains behind the success. I mean, Drew's years with the Saints weren't just Drew, we had some other great players, but the play calling and atmosphere was a lot Drew, and we assumed Sean. Time will tell.
We went 9-8 with 4 QBs, UDFA and practice squad dudes at WR, running back room of Kamara and others, and a 13 O-lineman rotation due to injuries. I don't know why anyone is questioning his coaching.
