The Bills offense wasn’t good enough, and it was their undoing in the playoffs. That’s how it goes. They need a few more players, and that was fully on display. They would probably lose to the Chiefs and the Titans in their current form. You don’t suddenly become a better team in January. They couldn’t get past the Texans, even with a 16 point lead. If they had a better WR, they probably score more than one TD in that game. If they have a Derrick Henry, than can close game out. So really, it’s pointless thinking about the what ifs when the Bills flaws were obvious.
