Hasn't been mentioned or discussed anywhere I've seen but the game was decided on a whistle that wasn't acknowledged. The Bills were piled up opposite the Ravens for a few seconds when Lewis ripped the ball from the Bills HB and covered it up.
Problem is, one of the zebras blew the play dead. One of the commentators even asked if a whistle had been blown. I heard it too. The other commentator quickly brushed the question aside... nicely too, I wish I had it recorded.
Whatever... who'd care it's only Buffalo, and the Ravens are a favorite NFL team of all. Now maybe I was hearing things but they sure ended the game quickly afterwards. It'll likely count somewhere down the line in Baltimore's favor.
Just thought I'd share my loony observation.
