Elevating Mrazek to #1 is a good idea and probably past due. Jimmy has been off since his injury. He is really reacting slowly...like he is moving in cement. Sit him for awhile.
Our best portion of the year was when Mrazek was #1 (after Jimmy went down against the Caps). While Mrazek can have a stinker of a game, he kind of exudes a certain confidence, reacts quickly, and moves the puck well. He doesn't play well every game, but he keeps you in a majority of games. Jimmy keeps you in a minority of the games (since his injury) which is not cutting it.
Goalies are streaky and I think you should rotate goalies in and out throughout the season depending on how they seem to be reacting to the puck and handling the stress of the position.
You need points...you can't just ride a guy forever because you have deemed him "the #1 goalie."
