RJ Umberger and the Ghost of Punch Imlach

If you haven't seen it, YouTube offers up the hit everyone is talking about: Brian Campbell's demolition of R.J. Umberger in the opening game of the Philadelphia-Buffalo series.

Incredibly, reports suggest that Umberger might not miss the next game. It seems that the modern, medically sophisticated, concussion-aware NHL reverts to its roots at playoff time. Call it the Punch Imlach mentality.

"If he can f**kin' walk he can f**kin' play," the old coach is said to have instructed his trainers. "But I don't want you sending him back to me unless he can f**kin' walk."
