Watch the Player, Not the Play - When the hockey player you're taking off is nearing the end of their shift, keep a close eye on him. Watch him wherever he goes on the ice. Don't take your eyes off him. When your player makes his move to change on the fly, it is up to you to be ready. Not having a drink of water, not tying your skate, and not watching the play at the other end of the hockey rink. Be ready........
