I have watched the play countless times.
No, Wayne did not "miss his block," he blocked him perfectly by walling him against the sideline, the DB was completely out of the play, which is why he was in position to have the ball come to him.
Patti did NOT "flung" it, and honestly, at worst it just sailed a bit on him and I am not convinced the defender that was crashing did not tip it.
No one is saying it was a GREAT QB performance, but it absolutely was a darn fine one, even before the final drive. Dude has 73 yards rushing, moved around to make plays, and made the big plays when they were most needed.
