I have always been a fan of Freddy. Being only a hardcore fan since around 2007ish (was a fan when Cujo and Belfour were here, but younger and didn't pay attention as much), he's probably the best goalie I have watched in a Leafs uni. He brought stability to a net that was patrolled by Reims, Bernier, Toskala, Raycroft and on and on.
It is tough to see how far he has fallen, even on the Marlies goals against posted earlier, he definitely seems off, lacks confidence etc. It would be crazy for someone aged 31, who was good within the last year and a half to be as bad as he is now, and not be able to get it back. I don't really expect him back in the playoffs, and based on his current play he shouldn't be expected back.
That being said, Campbell is our guy, and I don't see any reason to look elsewhere. If he plays as well as he has this year, goaltending should not be an issue in the playoffs.
