He also had a chance ti get at least 2 more if he didnt get greedy for the big one and stayed straight ahead. In the game situation that is what he should have done.
I am not saying it is all Cooper to be clear. But the fact is that is means Coleman isn't down in down out having to be the guy that runs down the field. It allows the Bills to diversify how they use him a bit.
It is also something that other McD's first year when they traded Dareus and got worse the Bills have generally improved at as they've gone further through the season.
And now he is in his right role. That is what he should be. An upgrade on Davis. Not the man expected to be your #1. No coincidence that since the trade he has broken out IMO.
