I was thinking about this earlier today when I was looking at the Pens roster in the early 90s. That team had three Calder winners in both of their cup years (Trottier, Barrasso, and Lemieux). The Flames also had 3 in the early 90s. Has any team every had 4 or more Calder winners at the same time? I know it is pretty much pointless, but I was just curious.
For however short a period of time, the Rangers had Leetch, Berard and Bure in 2001-02. And Toronto had Leetch, Nieuwendyk, and Belfour in 03-04. Can't think of a situation where there were four, though.
