Whistle-blower: Ron Wilson
Offender: Teemu Selanne
Offense: In April 2007, Wilson (inset) blew the whistle on Selanne for using an illegal stick during a Sharks-Ducks game. Wilson may have had inside knowledge, having coached Selanne in both San Jose and Anaheim.
Fallout: The ensuing illegal stick penalty wiped away Selanne's would-be game-winning goal for the Ducks at the start of overtime. Wilson's Sharks went on to win in a shootout.
