The offense has been bad because teams have figured out that you can just lock up the bills WRs in man because they can’t get open and Allen can’t run anymore. But they still have a lot of talent- good QB, RB, OL, TE (when healthy) so I think Brady and co. will figure some things out and steady the ship.
The defense is just devoid of talent so they’re sunk basically. Average is probably their ceiling.
