This isn't the first time that Matt Murray has been under fire for trying to exploit a rule of the league.
When a net goes off it's posts, it immediately stops play. This can come in handy when facing a high-danger situation.
While no punishment occurred when this was being spoken about earlier in the season, it appears Murray is back to his old antics.
This is live footage of a game. While it can be interpreted as him trying to fix the net during a TV timeout, it is easy to see this as a deliberate attempt to knock the net off it's posts, or loosen it for later on in the game.
