Once Emery quickly got the upper hand in this fight and Holtby was incapacitated I would have grabbed/tied up Emery's punching arm and slipped my chest and body in front of the Flyer fighter and skated him backward with my legs driving quickly and forcefully. I would immediately talk with the player to get his mind distracted and his adrenaline under control.

At no time when a player was taking a severe beating would I stand on the sidelines and allow it to happen without intervening, nor would I waive players away from coming to the aid of their teammate that was placed in a position of peril. I would assess the appropriate penalties that resulted from a third-man-in.
