As a Bills fan, I am excited to see this offense. Looking like EJ Manuel will start with CJ and FJax in the backfield along with a young but extremely talented group of WR's. Love Hackett's enthusiasm and he and Marrone obviously have a high paced innovative offense to put in place. 5 wide WR sets of Stevie Johnson, Robert Woods, TJ Graham, Marquise Goodwin and Da'Rick Rogers is just silly, throw in Scott Chandler at TE and EJ has some serious weaponry. Hopefully DM can work some magic with the mediocre O-line we have.
As far as the defense goes with Pettine, the talent is there, he has a lot to work with.
Lots of potential in Buffalo. Not saying this will necessarily translate to wins but as a long suffering Bills fan, with all these new faces, there is reason for optimism. One can hope!
