For those who missed it there was a discussion between Glenn and Wilson when Wilson came off the field after his late touchdown; it was quite animated on Wilson's part and followed by only a couple of minutes an announcer's statement that Wilson had been heard yelling towards the sideline to just throw him the ball, when he got few chances before that. To me it looked like it could have served as a wake up call to Glenn that his offensive staff was leaving his best chance to put points up somewhere below where he should have been in favor of a coaching decision to stay with a predetermined philosophy.
I think Hughes was making a joke because they got awfully close and cuddly. Who knows. Hughes is a weird guy
