My two favorite teams are the Spurs being that I'm a Texan. I pretty much love every player on that starting line-up, my favorite being Tim Duncan his consistency is a true testament to greatness.
My second is the the Boston Celtics. Even though Paul pierce and Kevin Garnett just got traded not to long ago. They are one of the most historic franchises and keep the old school theme alive as well. My favorite player there was Kevin Garnett aka the big ticket .
