Nah, Vladdy is an awesome guy at puck retrieval and stickhandling, I'd keep him there. Cally>Killer for PP purposes.
Yeah some valid points on Vladdy, just never though he was a major threat on there. But would certainly prefer Cally on the PP over Killorn no doubt. He is good in front of the net, and can get those pucks in the corners and get them back out to the points.
