If you follow the Montreal Canadiens at all, you'll know that Brandon Prust likes to poke fun at P.K. Subban, Brendan Gallagher, and especially Alex Galchenyuk. At practice on Saturday, instead of the usual pranks and roughhousing, Prust decided to imitate Galchenyuk during drills, it's a must see.
I'd say he's got Galchenyuk nailed there. So many head fakes and shoulder drops! If only Prust could keep the puck on his stick during it, he'd really be onto something.
