It depends on the refs point of view. If from a perpendicular angle then he missed it. If from straight on, then the hit was as the ball passed and legal. Multiple camera angles are tough on a ref. Generally, I thought they did a good job. The one thing I don’t like is the mugging that some receivers get.
There were two officials in perfect position. They saw it, and it was obvious. So much so that I jumped out my seat as though the Saints had won. There simply is no good explanation for the no call.
But hey, the NFL has it’s east coast vs west coast game.
