I agree with the Pats and SF being the apparent two best teams in the league with both being undefeated.
With respect to the Rams...they had so much talent on that team when McVay took over. It's like the current Browns. All they needed was a decent head coach.
The Bills had a huge hole to climb out of. Relatively little talent. Cap hell. Horrid front office. No QB. They surprised us all with making the playoffs in 2017 where McD did so much with so little talent. It doesn't matter that they needed help getting into the playoffs. The fact is they did, and the teams that should have been there, lost the games that would have put them in. The Bills won theirs.
Yesterday's game, no argument, was awful. Perhaps it's indicative that this team isn't good at all and it's been a facade, or it was just a bad game. I'm not willing to blow things up and declare McD an abject failure as a result. There are elements of this team and it's coaching decisions that I'd like to see improved. I'm willing to give them time.
