Ever hear of Simon Lajeunesse? The Ottawa Senators drafted him in 1999, 2nd round, 48th-overall. He was competing against Mathieu Chouinard for goalie of the future, but unlike Chouinard he actually got a game in with the Senators.
On March 7, 2002, the Ottawa Senators found themselves down and out in a game against the San Jose Sharks after starter Patrick Lalime allowed five goals on twenty-one shots. Lajeunesse played the final 23:30 of the game and didn't allow a single goal, giving him a save percentage and goals-against average unmatched in team history.
Enter October 2010. The Ottawa Senators, already down Pascal Leclaire, find themselves with no alternative but Brian Elliott. When Elliott's skate breaks at the start of the third period on October 16, 2010, rookie netminder Robin Lehner (drafted 2009, 2nd-round, 46th-overall) is forced into action for 4:42 and makes three saves on three shots. Two days later, Brian Elliott was pulled midway through a game after allowing five goals on twenty-two shots against the Pittsburgh Penguins, and again Lehner took the reins. Once again, Lehner was perfect, making seven saves on seven shots over 29:28.
Let's compare the numbers:
GAA: Lehner 0.00, Lajeunesse 0.00
Save percentage: Lehner 1.000, Lajeunesse 1.000
Games played: Lehner 2, Lajeunesse 1
Seconds played: Lehner 2070, Lajeunesse 1410
Shots against: Lehner 10, Lajeunesse 9
Saves: Lehner 10, Lajeunesse 9
Drafted: Lehner 46th, Lajuenesse 48th
Based on this massive sample size, I think we can safely say definitively that Robin Lehner is at this point the best goaltender in Ottawa Senators history. Save us, Robin Lehner.
