Absolutely!
They have beaten a grab bag of NFL stiffs, thus far and failed (not miserably- but failed) in their only significant test!
Don’t get me wrong. Prior Bills teams would not have beaten these teams they should.
They need much greater improvement on Offense to compete with the elite. The games against the Cheatriots, Philly, perhaps @ Dallas are the remaining mile markers! They should make the Playoffs. Let’s see if & how they improve weekly.
