The Swede who got off was basically over the boards already, and the Swede who took the puck didn't really even benefit from taking it before the other one was on the bench. Do you honestly think that's a call you make 10 min into a 0-0 quarter final game in the NHL?
I know it's a too many men on the ice penalty.
The dummy should have let the puck go since- as you said- he gained nothing by playing it.
