I've always enjoyed the Josh Allen show. Win, lose, or draw, it you don't have a real life stake in the game it's a fun ride. Unfortunately for him and Bills Nation, the things that make him such a gamble play right into the strengths for this Dallas defense. He'll have a good stat line, score a couple of touchdowns, but have a couple of potentially costly turnovers as well.
James Cook is the other member of this offense who I see as a potential problem. The Cowboys defense has had problems against the run, and he's been playing the hot hand the last few games.
The difference in this from playing the Bills in the past is their defense. They are not scary, not all that concerning really. As long as our defense can hold down Allen and Cook enough, their defense won't be able to do the same. It'll be close, but Dallas will continue the momentum in the end.
Final: Cowboys 30 Bills 24
