The voters are the GMs. As of now, Bobrovsky deserves it over Lundqvist and I'm sure the GMs know that.
Why does Bob deserve it over him, he barely has better stats? I'm not sure we're a better team than Columbus this year either. Also, if I were a GM I'd rather vote in Lundqvist and know I gave the Vezina to an established elite goalie than a guy that may embarrass me down the line when he turns into Jim Carey 2.0. That's just me.
