I'm a casual NBA fan, used to watch a lot, for last few years really only watched the playoffs. I skipped last year altogether actually. This year, really only the finals.
I'll classify myself as a Lebron hater in this series. I really route for whoever is FUN to watch. I liked Lebron with the heat actually, they were great to watch. Him with the cavs, brings out all his worst attributes, IMO.
They're FUN to watch, that's why. Team ball, finesse, unselfishness, etc.
