Three teams stood out to me, Pittsburgh, Buffalo, and San Diego.
The Steelers pushed Houston around and take apart your secondary on offense and terrorized them in a feeding frenzy on defense. The Steelers we know and love
Buffalo was also reminiscent of past quality Bills teams, productive in all three facets of the game. The fake FG is a great sign to me that this group has the mentality of a winning team from the coaches to the special teamers. Edwards is a good game manager, Lynch is a ball control back, and remember, they didn't have Peters against a very tough pass rush.
San Diego's defense was not as impressive as previous versions, but they did collapse the pocket a lot, and they have the potential get rabid like the Steelers. They get Stephen Cooper back in three weeks. The secondary is young and will continue to get better. Rivers basically willed the team to victory in the 4th quarter before Delhomme answered with a victorious crusade of his own. LT is still LT. And they were also missing McNeill. They will have something to say.
These teams look the closest to complete.
The Steelers offensive line is far from a strength and the D can be defeated through the air if the pressure is kept at bay. The Bills have a ho hum offense and the loss of Crowell hurts. The Chargers were the AFC runner up last year and a healthy Rivers might have taken down the Patriots, so they're the new favorite in my book.
