An incident between John Tortorella and Philadelphia Flyers defenseman Cam York this week contributed to a deteriorating relationship between coach and team that led to Tortorella’s firing on Thursday morning, a team source said.

With Tortorella out, all attention turns to who replaces him. Danny Brière and Co. say first and foremost, they are looking for a "teacher" to work with the team's young core.

Flyers reporter Kevin Kurz says that John Tortorella and Cam York "crossed the line" ahead of the coach's firing on Thursday.
