I thought that call was for helmet to helmet? I was in the stadium and couldn't hear it but thats what I was told later. If it was catch interference they TOTALLY blew that one and deserve to get downgraded.
The ref called fair catch interference. The fans probably couldn't hear him because they were (justifiably) booing so loudly. It was a badly blown call.
I was listening to the game and on that call I distinctly remember the ref saying it was a personal foul...helmet to helmet contact. Then the announcers went on about how they are calling things like that more. But the call was helmet to helmet.
Not sure where you heard that. The TV announcers went on and on about how he wasn't anywhere near the halo violation, and they even showed a slo-mo of the play and showed how far away he was from the receiver. I may have been distracted by beer and conversation, so you could be right, but I was pretty sure they said it was a personal foul, interference with the ability to catch the ball. Since the halo violation is a 15-yarder as well, it seemed like the call they were making.
