As a team, the Edmonton Oilers of the 1980s were one of the best collections of talent the NHL has ever seen, winning five Stanley Cups -- four with Gretzky -- between 1983 and 1990.
Four members of those Stanley Cup winning teams, including Gretzky, went onto become head coaches in the NHL with mixed results behind the bench.
-- MacTavish had the longest tenure as a bench boss in the NHL, coaching the Oilers for eight seasons before being removed from the position following the 2008-09 campaign. During his stint, the team qualified for the postseason only two times, advancing beyond the first round once when the Oilers went to the Stanley Cup Final in 2005-06, losing to the Carolina Hurricanes in seven games.
-- Like Playfair, Lowe was only a head coach for one season in the NHL, leading the Oilers to a 32-16-8 record after replacing Ron Low. The following season he was promoted to general manager, replacing Glen Sather.
-- And then there's Gretzky's rather infamous, and forgettable, tenure with the Phoenix Coyotes.
Just for fun, here's a sampling of some Hall of Fame players from hockey history and how they succeeded -- or failed -- as head coaches in the NHL. Please keep in mind that this isn't every Hall of Fame player that went onto coach in the NHL, just some of the notable ones. And we're really going back in time with some of these examples.
