The MAIN reason? There wasnt one. There were many resaons as to why they lost that game. The O-line sucking was only one reason. So don't start that crappy argument again.
Im' not a huge fan of the o-line, but i find it hard to believe that they turned to crap one season removed from being REALLY good. You cannot say that it was all Brady during the 07 season. There were times when they snapped the ball, Brady dropped back, called Gisele on his cell phone, waved to her on tv, and then launched the ball to Moss 80 yards down the field. There were alot of times that Brady just stood there thanks to great protection.
Now, as for last season. I don't get it. As some have pointed out, maybe they needed to get used to Cassel. All I know (being a casual homer fan) is that they looked aweful, then Neal comes back, and they start playing better. Linemen always say that its nice to have some stability on the line. Maybe it wasnt as much Cassel, as it was Neal. Not that that helps when he gets injured again. Either way, Im satisfied with our starters, just not the backups. Though I did like what i saw from Levoir when he was in.
