The crappy calls at the end(pass int and the "catch" made by meatchem) were pretty blatant. But, the vikings fucked the game up pretty bad anyways. I think it was 5 turnovers... and the Saints only won by a FG in OT. This was a bad game by the saints, but the vikings actually played pretty well when they weren't practically giving the ball away. It was a pretty fun game to watch, but the quality of the game was down, IMO.
That being said, I do feel bad for the saints. They looked so happy when they won that game. Fate has seemingly gave them a chance to win the Superbowl... only to have them come crashing back to reality when they face a consistently good team in the Colts. The saints are going to get their asses handed to them. Manning vs. Brees? No contest.
