I was just about to say, it's working out a lot better than I thought it would. If he dominates at C until Dvo and Chucky are back, there will be some very interesting decisions to make.
I don't think it'll be that much of a controversy. I'm only going by public comments by players and management, but I don't think Keller personally cares if he plays wing or center. Personally, I think he's so talented that he can thrive at all three forward positions, myself. At the end of the day, having so many players who are good at center that you have to shift some of them to wing, but those players also effective on the wing, is a good problem to have.
