The NHL used to be defined by dynasties, at the team level and in some award categories.
The League's recent history has shifted toward parity. No team has repeated as Stanley Cup champion since 1998, and no player has successfully defended a major individual trophy (Hart, Vezina, Norris, Adams and Selke) since Pavel Datsyuk won the Frank J. Selke Trophy for a third straight year in 2010.
Patrice Bergeron has won the Selke twice in the past three years, and he is NHL.com's preseason favorite to earn the honor in 2014-15. Should he do so, Bergeron would become the fifth player in League history to win the Selke three times, joining Bob Gainey (four times), Guy Carbonneau, Jere Lehtinen and Datsyuk.
