The coaches get the players ready to play. That's all they can do. For whatever reason, the previous regime couldn't get these players to play, or at least not all of them. This one can, or at the least, the players have grown since last year. The players are playing with confidence, finally. If all teams had the same level of talent, all that would matter is how well they execute - and if everyone did what they needed, we would have 32 ties every week, because noone would go anywhere.
We have more talent than all but a few teams in the league. They're finally playing like it. Pin that on whatever you want, I'm just glad it's finally happening. And it should continue to develop, in line with the thread, as winning breeds more and more confidence.
