I think this is a matter of personal taste, like if they asked you, who would you choose, Hitler or Stalin? Well, if you're a person who wishes short mustaches made a comeback, you would probably go with Hitler. If you always had a thing for short people, then Stalin would be your choice.
In my case, I will go for the Celtics. I know I know,they're a bunch of jersey popping jackasses who's cast includes Ray Allen, the proud owner of a mangina, Paul Pierce, who suddenly gives a shit about playing defense, and Kevin Garnett, who's on court "intensity" is like a porn star's moaning, meaningless. But I just can't bring myself to go for the Lakers. The Celtics are annoying as hell, but what about a team headed by Kobe "now trade me now don't" Bryant? The guy wanted to trade the Lakers future for Jason "yeah, I beat my wife a little" Kidd for fuck's sake, and he would get rewarded for that with a ring? Call me old school, but I can't root for a psychopath. I guess they don't make them like me anymore.
So who will you go for? Celtics or Lakers? Or world destruction? Or will you ignore the NBA Finals are happening and just think happy thoughts like the psychologist told you?
I think one thing we can all agree on is, looking at the Celtics and Lakers, we have to be glad we're Spurs fans.
