For those whining about the non call at the end of the game, does anybody remember the non call at the end of the first quarter on 2nd and 13 when Flacco aired the ball out down the right side of the field (I believe it was to Torrey Smith), and he was held be Chris Culliver. Phil Simms even commented that had he not been held, Smith would have caught the ball in stride and scored.
So, like others said, there were calls and non calls for both sides. And even on that last play, there was contact coming from both participants. How do you rule who is "more at fault"? If it's offsetting, it's just going to reset the play anyway...and then the same thing is going to happen when you replay the down. I will say that the Ravens were fortunate to get out of there with a win after the way the team let Flacco down in the 2nd half (fumbles, dropped balls, o-line disappearing, missed tackles), but anybody that thinks the 49ers were cheated out of a win is nuts. They shot themselves in the foot NUMEROUS times (first play of the game, illegal formation wipes out a 20 yard gain, ultimately forcing a 3 and out...defensive holes...timeout management...etc)
Honestly, had it not been for the blackout, I don't know if they even come back in that game. It's a really weird thing to have to consider, but that 40 minute break gave them a chance to calm their emotions and start fresh again. If they came all the way back to win, I almost feel like the game would have been tainted because of it.
