That is a very tough call and pretty much a pick 'em for me. Both forwards are getting every opportunity to succeed since they are newly acquired players to their respective teams. Having watched every game of Hudler's I would side with him though. Hartley is letting the Flames play a fairly open offensive game and Hudler has taken advantage with his creativity. And as of right now, Hudler is supported by a better overall cast of players. The Avs are just too injury riddled to have great offensive numbers for the foreseeable future, and with a weaker supporting cast for Parenteau I think his numbers won't be as good as Hudler's.
