Not current, but growing up for whatever reason I really hated Michael Jordan. I think it was because everyone else loved him, and my team was the mid-90's Magic. I hated him so much that I'd trade away any Jordan (or bulls for that matter) basketball cards I got for not a lot back in return.
I have a great appreciation for Jordan now, and am in the camp he's still the best ever, F LeBron.
So I guess my current would be LeBron. Honestly, he made bad PR move (the decision), and it's followed him ever since. Not sure he really deserves it, but I've never wanted him winning any championships.
