In the Minnesota-Detroit game, on the exhilarating final play, Parry had one player to watch -- quarterback Joe Webb. And while Webb floated to the left trying to make a play as time expired, Detroit linebacker DeAndre Levy grabbed Webb's facemask and twisted it. Clearly a flag should have been thrown. No flag. Levy sacked Webb, the ball was fumbled, it got kicked around, and the game ended.

What should have happened: The Vikings should have gotten an untimed final down from the Lions five-yard line (half-the-distance from the spot of the foul, which occurred at the 11).

The non-call could play a major role in the NFC playoff race. The Lions are 8-5. We'll never know if they should be 7-6. Now, who bears responsibility? Parry's sole job is to watch the passer, but the ref was shielded because Webb's back was to him. Bowers' job is to watch Toby Gerhart and action in the offensive backfield. So I'd say Parry should have been able to see the severe twisting of the helmet and assumed the only way it could have been jerked like that was grabbing the facemask ... and he should have been backstopped by Bowers. As it was, a huge call with playoff implications was missed.
