Well I can certainly understand why you like OKC; basically all of my friends that like them as well have the same reasons as you. I'm from Canada and was born in Toronto so naturally I'm a big Raptors fan. :P The Lakers are my 2nd favourite team, mainly because Kobe's my favourite player ever.
And yeah, management made a huge mistake trading Harden away so they could sign Kendrick Perkins, especially considering his breaking out in Houston and the fact they only got a mid 1st round pick and one year of Kevin Martin in return. I feel like they're going to drop a little this year because of Westbrook's recovery. As for breakout teams, I'm definitely going to watch for Cleveland this year, and maybe New Orleans as well.
