…and in case you were wondering how “control of the puck” was defined, here you go!
“Control of the puck” means the act of propelling the puck with the
stick, hand or feet. If while it is being propelled, the puck is touched by
another player or his equipment, or hits the goal or goes free, the
player shall no longer be considered to be “in control of the puck”.
