I accept that refs make spotting errors, but it's not relevant in this case: the ref wasn't fooled, the touchdown had already been scored by the time Ben landed and then reached forward with the ball.
You can't fault the ref for making a human judgment.
Why would I fault him? He got it right.
Then why doesn't one of the hundred of video cameras and thousands of photographers have one picture of the ball breaking the plane???? Probably because he either missed by an inch or his arm was in the way. The is great video evidence, but none shows the ball breaking the plane. It would have been absolutely impossible for the line judge to see the ball breaking the plane from 20 yards away. The line judge only saw the ball in the end zone when he ran up after the play was dead. I am absolutely correct on this and you have zero evidence that refutes it. I really don't see it takes away from the Steelers victory, Seattle let them get that close, it is their own damn fault for allowing the TD whether Ben crossed the plane or not. You can't count on a ref for a perfect spot.
