Definitely Timberwolves
Born in Boston, then moved to Minnesota for a couple years before coming to the Bay Area. Garnett was drafted when I lived in Minnesota and I remember watching his game develop from a teenager into his prime. Guy ALWAYS brings it on both ends of the floor and is one of the most passionate, loyal, and unselfish players I've ever had the pleasure of watching.
A couple stories some people may have forgotten about KG; During his MVP season in MN, SI asked him to be on the cover of their magazine and he refused unless Sprewell and Cassell could be on the cover with him. Then, during his first season with Boston, he was asked again to be on the cover. Again, he refused unless Ray and Paul could be on the cover with him.
Theres absolutely no doubt in my mind had KG not injured his knee in 2009, he would have atleast 2 more rings in his collection. And had he been traded out of MN earlier, then anything could've been possible. Many, including myself regard Tim Duncan as the greatest power foward to ever play this game. But IMO, KG is right up there with him.
