4 — Difference in the number of goalies dressed by the Flyers in the 2009-10 season (7) and the 2010-11 season (3).
Sergei Bobrovsky, Brian Boucher and Michael Leighton have shouldered the load on their own this season, while ’09-’10 required the talents of Boucher, Leighton, Ray Emery, Johan Backlund, Jeremy Duchesne, Carter Hutton and Game 82 MVP Sebastian Caron.
Put another way, the Flyers have dressed one fewer goalie in 2010-11 than they dressed in the 2009-10 team picture.
