Josh Allen went 20/26 for 194 yards and 2 TD vs the Packers in the final preseason game.
So he's still the same Josh Allen, it's just that defenses are scheming up ways to disrupt the Bills passing attack. You want the team to peak in January/December. This is glorified preseason right now.
I saw this on a Patriots message board, and I though it was an interesting stat:
In 6 super bowl winning seasons, the Patriots went:
2-0 twice
1-1 three times
0-2 once
So the key is to bank these wins early, by any means necessary, then be hitting on all cylinders come December and January (and hopefully February!)
