In that circumstance, what was the benefit of pretending to be injured? The puck was in the corner and the goalie was on his back in the net. Never seen a goalie fake an injury when the puck is in a non-threatening position.
You’re welcome to disagree, but we have the benefit of hindsight to clearly see that the player wasn’t able to return to the game. This shows that the ref made the wrong judgement call on the play.
The benefit in his head was likely two fold. Firstly, maybe they call goalie interference and his team gets a powerplay. Secondly, he likely feels they'd blow play dead whilst the opposition have the puck in their zone.
I don't think he's faking it for what it's worth, but you asked the question. There are clear and obvious benefits to staying down. Again, if you start calling play dead whenever a goalie goes down they will do it all the damn time. In reality, let it play out and then review it for goalie int later on if needed.
