Title pretty much explains the video content. Avs first goal probably enters a gray area of goaltender interference. If Rinne is in the blue paint and Ellis is pushed into him that would CLEARLY be interference. But since Rinne pushed out of the blue ice the call is more unclear. What is crystal clear however is that Landeskog's push on Ellis DID cause him to fall over Rinne and open up the net for an easy goal. If he doesn't push Ellis then Rinne would have had a much better chance to save this shot.
