|2008-2009||Columbus Blue Jackets|
Few goaltenders have been drafted into the NHL with less experience than Mason, who was selected by the Columbus Blue Jackets in the third round (No. 69) in the 2006 NHL Draft after having played just 12 games as a rookie with London of the Ontario Hockey League.
The Blue Jackets never considered the move to be much of a gamble, and it paid off for them when Mason won the Calder Trophy as the NHL's top rookie for the 2008-09 season. Mason also helped guide the Blue Jackets to their first Stanley Cup Playoff appearance that season, when he had 33 regular-season wins, a 2.29 goals-against average (second in the NHL), a .916 save percentage and a league-leading 10 shutouts in 61 games (all starts).
