Incidental contact, at best. He was not shoved full bore into the net. In fact, he was actually moved into the post, not the net (watch the replay). The goal was the incidental part of a legal play/scrum for a loose puck. The ref did an A+++ job being in the right position the entire time to see the puck and the play as it evolved. As bad as we all complain about the refs, he was in the absolute best position to see the entire play. All kudos to him.
The only whining from the SJBabies bench was based on the thought that Stalock at it covered, as Cheatin' Joe Thornton admitted in the post game himself. There was no complaining about him being pushed into the net. They thought the puck was covered. So did Drew Remenda, as he whined himself through the last ten mins of the game and post-game. They didn't have the right angle, nor see that the puck was loose. Had they, there would have been no complain, even from that bunch of babies.
You're trying to hang on to a weak technicality, which no one is even disputing.
