I give him an incomplete so far. His moves on offense, hiring Roman and pushing for Tyrod, have played huge dividends. Best offense we've seen in forever.
The reason why he's an incomplete is because the defense sucked last year, and he mishandled a defensive transition that people in the know said would take a good year anyway. So while he screwed up, I'm planning on giving him two years to get his scheme in order.
As far as Rex the person goes, he seems like he would be a super fun coach to play for and I feel like we needed someone with his personality to fire everyone up after Marrone.
