First, from Jeff Marek:
There has been some speculation on the future of Petr Mrazek with the Vezina-like season Jack Campbell is having. I checked around on this; there has been no discussion that has been initiated by the Maple Leafs about Petr Mrazek. They see him as part of the program for this season.
However, there have been some teams who have called the Maple Leafs and said, “if you are looking to make a move with that goaltender, give us a call. We are interested.” Very much, there is a marketplace for Petr Mrazek.
