You know....and I'm getting clowned by my family and friends about me being bias saying this.... yes it was a penalty.... but it was a hell of a lot closer to not being a penalty than people are seeing. The reason why the ref didn't throw the flag was because Robey got there about the same time the ball got there...he got there just before the ball was at the receiver....it really was a bang bang play.... and no it wasn't helmet to helmet, or defenseless receiver either...he hit him first with the forearm to the chest....
it's the angle from behind that makes it look like he got there super early...when you look at it in from the original angle...he gets there pretty much as the ball is getting there...
