Not really. Must be at least 8/10 times that a team scores while having a 4 on 3 in OT so it makes perfect sense to pull your goalie when you've established yourself in the offensive zone. I've been waiting for a NHL coach to do this for two seasons now since TImrå in the SHL did it twice in a row and won both times.
This is pretty old, but:
53% is very high compared to normal 5v4 PPs. Unfortunately, this is literally the only stat I can find around it, and compiling it by hand would be an arduous task. This is also probably wrong to some degree, since the team with 3 players can't ice the puck without consequences in a goalie-pulled situation. Of course, that's minimized a bit because obtaining the puck in order to ice it is harder in a 4v3 anyway. I would think 60% is a reasonable figure for the success rate of a 4v3 in OT.
So...
- The risk to the Wild is that they could get 2 points in the standings, or 0 points.
- The Predators can get 2 points in the standings, or 1 point.
For this to be an acceptable risk, it needs to succeed at least 66.6% of the time, due to the opponent not having any risk by still getting the OT point. For it to overcome natural risk-aversion, it needs to be even higher, the exact amount dependent on the individual, but overall I'd guess around 75-80%.
60% just wouldn't cut it, but again, that's a figure I pulled out of my ass that I think might be reasonably ballpark, so unless someone who does this for a job - or has no job - wants to do it, we'll never know the real rate.
Personally, I think it was a risky move, ballsy as hell, and I love it.
