Ill go with that. The only reason I said it had meet that criteria is purely because if he didnt go behind the back the shot would of went wide. so it wasnt going in if he didnt try or missed unless he fucked up and slapped it in off his glove.
That was all luck and quite possibly the worst play he could have made. I hope he got a tripping penalty.
As for the original post, I don't know if I would say it was the best save ever. It was a very impressive save, but as it was pointed out earlier, it may have gone wide if unimpeded and technically isn't a save. For argument's sake, let's say it wouldn't have gone wide, he was out of position. The didn't come off of some rebound or a crazy pass play, it was a fairly routine couple passes to the backdoor that he was out of position for. The puck shouldn't have been behind him in the first place.
