I was listening to Panthers Talk earlier in the car while I was out and Rivera said his interpretation was that if a whistle is inadvertent then the refs have to decide whether the whistle affected the outcome of the play and they determined that he would have scored regardless so it counted.
It ccould just be my imagination but, I could swear the only whistle I heard was one short tweet. Kinda like he was going to call DWill out of bounds before he actually went out of bounds. Started to blow the whistle, then tried to stop.
Talk about your nadvertent whistles.
