The Chip Kelly era turned so bad so fast that it is easy to forget that his offense resulted in the two highest-scoring teams in franchise history. He won 26 games in three seasons with Michael Vick, Nick Foles, Mark Sanchez and Sam Bradford at quarterback. Foles, Sanchez and Bradford all seemed to operate his passing concepts with ease. All three had their most productive NFL seasons under Kelly. Kelly's weakness wasn't that he was a dummy. It was almost as if his mind moved way too fast to enable him to take a step back and look at the big picture some times. But that doesn't seem to be a problem with Shurmur, who showed that, at the very least, he was an active enough participant in Kelly's offense that he could run it for a day and make it look even better than it did under Kelly this season.
