For a few years now the Bills have not had enough difference makers. Allen on offense masks a lot. On offense, I think Cook is the only difference maker. The whole online is really good too which is huge.
On defense, maybe Benford and Bosa has potential. I'm not sold on Oliver; he flashes in some games and then disappears in others.
I think it's a great roster for the regular but come playoff time the Bills lack of a difference makers has certainly hurt them. We will see how it plays out this year.
On the downside, I still not encouraged about McD's ability to get over the hump and lead the team to a SB. I think it's Allen willing the team to the SB despite of coach McD. Similar, to when Flacco led the Ravens to a SB win.
