KG is definitely outside the norm when it comes to chameraderie in the league. I would put Kobe in the same category. With me or against me...no in between.
It's a real difference between the mid 90's draftees and the younger generation of stars (Lebron, Wade, Dwight, etc.)
I actually prefer the respect that younger players have for their peers. I think KG calling out a starting point guard on a team that's ahead of his in a playoff race lacks class.
Reminds me of this story:
Garnett wasn't exactly welcoming to Pacers rookies A.J. Price and Tyler Hansbrough when he visited Indianapolis this summer to film a Wheaties commercial. As Garnett exited Conseco Fieldhouse, Indiana assistant coach Lester Conner asked him to walk over and meet Price and Hansbrough, who were working out. Garnett wasn't exactly friendly. According to Conner, Garnett continued to walk out and remarked, "[Expletive] your rookies."
This is the side of KG that I don't care for.
