I actually think Marrone seemed like a pretty solid coach. The Bills are stacked with defensive talent but he did seem to get the most out of it. They gave us fits for two years.
That said, wow is this an indictment of EJ Manuel. They must have no confidence in him at all.
Actually my read on it would be that Marrone wants to move on from Manuel -- his staff is the one that benched him, after all -- but that management gave him some kind of indication that they either want Manuel groomed or they otherwise don't like his plan at QB moving forward.
Bills fans seem to be thrilled by this. A few are calling for Frank Reich to be the new coach. While others seem to think this is nothing good for EJ Manuel..... don't know about that.
