New York Rangers beat New York Islanders 2-1 april 5, 1990 at MSG and Ken had someone in his 'bombsights'. Why today? Because Deadspin has a great fight video today, Mudbugs vs. Ice Rays Is The Greatest Rivalry In Sports and Dashiell Bennett asked for "If you've ever seen two hockey teams more itching to fight than the two squads in this video, well ... find that video and send it to us."
Extra juciness? Ranger Jeff 'The Wicker Man' Bloomberg was a Born-Again Christian who didn't fight...so he was put on the ice as a sacrifice by Roger Nielsen?
Here you go. Itching defined.
