Liam O'Brien breaks his stick over Sammy Blais then chases him all over the ice before tackling him

Today's Lesson: Don't piss off Arizona Coyotes forward Liam O'Brien.

Because if you do, he's liable to chase you around and and choke you out. At least, if you're St. Louis Blues forward Sammy Blais because that's almost exactly what transpired this evening in tonight's game between the Coyotes and Blues at St. Louis' Enterprise Center.

Clearly miffed by something, O'Brien chases down Blais, breaks his stick over him and then and wrestles him to the ice:

I'm pretty sure Blais didn't even know that O'Brien was chasing him lol

You've just gotta love O'Brien. The guy is an absolute animal.
