San Antonio teams were better than Minnesota, they were more well coached and they were better defensive teams. KG was the only good defender on his team, outside of '04, the Wolves never ranked in the top 10 defensively, if you replaced KG with a league average PF they would probably be a bottom defense.
In those Celtics years, Tim Duncan didn't win shyt either.
Also, Tim Duncan WASN'T a PF in those Celtics years
KG got a chip, and if he didn't get injured in '09 they could have potentially repeated as that team was on a 70 win pace, then LeBron went to Miami and shut the East down and after '12 it was a wrap for Boston.
I didn't say anything about coaching because there is no denying Duncan had the advantage there. We were clearly talking talent and there is plenty of evidence that Duncan's advantage there is nowhere near what folks try to make it seem. In those Celtic years Duncan wasn't playing Pierce, Allen, and Rondo . Duncan was the main reason the Spurs were so good defensively year in and year out, as he was the anchor for years.
