Thats what nantz said, but not the officials. There was also an angle (that i think they only showed once on the broadcast) that seemed to show pretty clearly it didn't hit the helmet.
The thing that bugs me the most is they need to change the rules to just eliminate the stupid official from the review. If the clown got it wrong on the field why is he even in the equation for the review. Just go to an eye in the sky - 99% of the time people sitting on a couch can tell clearly from replays - just look at the replays and make the call - no need to have the idiot official who got it wrong standing there looking at a tiny little screen for 10 mins
