It’s a saying that Detroit Red Wings goaltender Petr Mrazek hears often from his dad, a former professional soccer player: If you’re on the train, once you jump out, you can never catch that train again.

It’s a thought that comes from experience for Mrazek’s dad, whose professional soccer career ended when he missed a year with a serious injury. He spent a year in the hospital, according to Mrazek, and had seven surgeries on his arm.

“That was over,” Mrazek said when we chatted following Tuesday’s practice.

The train ride can end quickly, especially in the NHL for goalies. We don’t have to look far back to see great goaltending stories that fade away to history. Just last season, you had guys like Michael Hutchinson, Andrew Hammond and Eddie Lack looking like they could be establishing themselves as future No. 1 goalies in the NHL, and that may still happen. But right now Hutchinson has a .904 save percentage, Hammond is at .912 and Lack is at .891.
