Of course it's arguable, because that's why they play the game. Otherwise Bills should have been handed the Lombardi last June because they won the offseason.
On paper, the Bills talent is worse today than it was last Friday. But I'm not going to make a prognostication that this team will fall apart if it jumps out a 5-3 start. I'm looking at a top 5 offense which didn't lose much production in the departed vets, and a defense that squandered 4 second half leads. If they hold on to two of those Ws, plus don't trot out the EJ experiment in the finale, it's a playoff team.
Last year's squad went 1-4 to close out the season, with the missing talent you're referring to. Maybe there was more to it than the talent?
