I like Footballoutsiders.com because of their statistical approach to the game. They take every play into account and adjust according to opposition strength. In their week 8 rating that just came out, the Niners rank 18th overall, up from 21st last week.
The good news is that the D ranks 6th, 11th against the pass and 3rd against the run.
The bad news is that the O ranks 22nd. However, the passing game ranks 19th, and if Alex had thrown enough passes to be ranked with the other starting QB's, he would be right up there with Peyton, Brady and Brees. Of course his last 2 games might be an aberation, and one would expect that he will regress to the mean.
The running game ranks 27th out of the 32 teams. Only Houston, Chicago, KC, Arizona and Seattle have worse running games. This is reality, and it certainly conflicts with Singletary's notion that the Niners are a running team. Hopefully, he will soon face reality and adjust.
