Honestly folks, the Bills aren't that bad. If not for key injuries...and the fact they lost their starting LT in FA......oh, and could finally get a decent Qb...they would be pretty good.
Def is solid when healthy, but losing two starting Cbs for a time, and your best S, and LB and some DL and you don't do as well.
Having Off. tools like Lynch, Jackson, Owens and Evans also is a plus. Just need a Qb to pull the trigger and USE those tools.
