I was hoping someone would mention the Dave Bolland breakaway in OT that sent the Leafs over the Oilers, 6 to 5. The goal itself was pretty, but the means to set it up were quite goonish. Take a look at the punch to the back of the head on Ryan Nugent-Hopkins and explain why there wasn't a call. Getting mugged in front of 20,000 plus an international audience with absolutely no consequence is pretty amazing.
(the mugging comes 5 seconds in)
I'd love to hear your comments on this one.
