Corson Quits

I had no idea you could leave a team in the middle of the playoffs. I guess you can, though. Shayne Corson resigned from the Leafs. Apparently he’s pissed about being a healthy scratch.
I’ll never understand the idea of quitting or holding out because of lack of ice time. I mean I’m no hockey expert, but isn’t even harder to get ice time if you’re not playing?
Actually, I heard the Leafs took Corson’s resignation letter, crossed out Corson’s name, and filled in Phil Housley’s name.
