Hmmm I don't know the rule but I thought that if a scrambling qb is out of pocket, there is no defensive holding or illegal contact downfield.
However, the push happened while the ball was in the air. In this case, PI should be called.
Regarding the intentional grounding, the refs can argue that there was so much pressure that Peyton underthrew his receiver or that the receiver ran the wrong option route
From what I remember seeing, the receiver was where the ball landed right before Peyton let it go. Still should of stopped them on 3rd down.
