Great question. I think Alfie will dominate as long as two things fall through, namely 1) he stays healthy and 2) he doesn't rotate lines too much. I think the success of the others hinders on his performance and therefore he is my pick.
Alfie is my pick for the same reasons as Alex. He is simply almost always in on the other guy's goals. Don't forget he was leading the league in points prior to going down with his hip injury a week or so ago. I have to also mention that Alfie is one of the best pin point shooters in the league. This guy almost always makes the goalie come up with an excellent save or it's in the net. He is one of my all time best players to watch. Put simply, he is sneaky good.
