First off I'm not blaming this loss on the officials, the Steelers defense allowed it, plain and simple.
Beyond disgraceful, beyond pathetic, beyond horrible officiating tonight from Walt Coleman and his entire crew. Regardless of the outcome, there is no excuse to miss that many calls and at crucial times. You are paid to make the calls, make them. I don't care if it's a judgement call or not, helmet to helmet is not a judgement call. When the guys' head snaps back and you hear a big CRACK, that usually means somebody's helmet hit somebody else's helmet.
There were atleast 6 blatant holding calls that were missed against the Ravens secondary. Wallace, Heath, and Brown all were held so many times it wasn't even funny.
Apparently though it's ok for Ray Lewis to have helmet to helmet contact but it's not ok for Ryan Clark. Both should have been flagged, and both were out in the open. It wasn't like there was a sea of bodies around that shielded their view.
