Yeah that's what I saw too. Though the refs didn't see any. They were too busy calling offensive holds on the Broncos all game.
In my opinion the phantom hold against the Broncos on 3rd and 1 in the 4th quarter was every bit as game changing as the Broncos blown coverage at the end of the game. Instead of having 1st and 10 at midfield with a touchdown lead and momentum the Broncos end up at 3rd and 11, which led to a sack and a fumble, and then a tie game. If the refs weren't looking so hard for Bronco penalties all that game the Ravens lose by double digits.
