We beat them by 20 points

i know but the "experts" are making it seem like it was down to the very end

Well, it pretty much was down to the end. It was 10-7 going into halftime, and remained that way for the entire 3rd Quarter, until 9:55 left in the 4th when PT broke his first TD run.

Now, while our D held Trent Edwards and the Bills' offense to pop-warner ball numbers, our offense failed to click for a good portion of the game as well. Brees seemed to be hurried much more than he has in previous games this season, but then again we were down to our third LT, and, iirc, Streif is actually a RT behind Stinch, who had to play for the injured Bushrod. The run game exploded in the second half when the Bills D was worn down and our O-line just got stronger, but early in the game when we were trying to throw more often, Drew had people around him more than he was used to.

Also, I seem to remember that the Bills fans were not unhappy with the loss of Jabari Greer in the offseason, citing the fact that they had some killer DBs in McKelvin, McGee and Whitner, which fact was shown today, as Brees had problems finding open receivers when he did have a time to throw. Remember there were a few plays when Drew had enough time to enjoy a cotton candy while trying to find a receiver, that meant the OL was doing a great job, but the DBs were blanketing the receivers.

All in all, it was a close game until the mid-4th quarter, as the Bills were always in striking distance, they just failed to execute when they had chances and our D didn't give them many.
