Were the Ravens the luckiest team to ever win, they got like every bounce and break.
plenty of calls and bounces went against them (or at least non-calls). Clear pass interference against Smith early in the game was not called. Flacco was hit at least a full yard out of bounds (should have been a penalty). Missed the fake FG run by a yard. 3rd and goal from the 1, they pass and then kick a FG. Flacco is sacked taking the team out of FG range. With momentum clearly to the Niners, Rice coughs the ball up. etc.
You can do the same thing with the Niners, but it isn't like Baltimore got every call or every break in the game.
