I was never really converting to the Jazz, I'm still a Bulls fan. But I'll absolutely be cheering for the Jazz if Dee or Roger Powell makes the team, and for that matter, even if not because Deron's still there.
I don't feel as bad about it because the Bulls come well after the Illini and the White Sox to me, always have. I'm still very much a Bulls fan, they just come in lower on my fan totem pole. Still above the Bears, though.
