Cossa made 27 saves in a 3-2 victory over the Maple Leafs on Tuesday.
The big netminder is on a roll. Cossa has won three consecutive starts and twice in the last two weeks (2-0-0; five goals allowed). That's material because starter Karel Vejmelka is 0-2-0 with eight goals allowed in that same span. There's no netminding controversy yet, per se, but the Mammoth could alternate goalies short term if Vejmelka can't settle his game and Cossa continues to step up.
