I think you can blame him, given that the Saints were twice in a position to win the game in the final four minutes or so. The offense scores to take the lead, and the defense lets SF march right down the field and take it back. With less than two minutes to go, the Saints' offense scores again to take the lead. The defense responds by allowing SF to go the length of the field again and score the winning touchdown. The Saints' defense had no answers at the end of that game, and neither did SF's-- New Orleans simply ran out of time.
