I'd have to say the Kings. I've watched two of their home games this year, and they were both intense.
Suns 1. Loving watching the fast run 'n' gun play 2. Interested to see if they are for real, sorta like the Denver Broncos of the NFL.
Lakers. Not because I like the yellow and purple bastards, but they always get the best effort from their opponents and the crowds at their road games are fantastic.
