I mean, if you look at the last few games the Bills have been the ones who've put themselves in a bad position countless times. They've beaten themselves more than the opposition has beaten then and if you think different then you're not watching the games.
Sure, they've been disappointing, but to say they've been outmatched is pointedly wrong. Though, I'm sure your expert analysis is spot-on and I'm way off base here, but the Bills have done everything you've said they haven't and still lost close games.
If they're as bad as you claim, these would've been blowout losses.
