It is no secret that Detroit Pistons star Blake Griffin holds some ill will against his former team, the Los Angeles Clippers. It has been almost been a year since Griffin was traded to the Pistons in the middle of last season, but it appears the 29-year-old still feels a bit aggrieved.

Clippers head coach Doc Rivers recently admitted that he has not spoken to Griffin since the move, but also went on to explain why he does not consider this to be a big deal.

“I haven’t spoken to him,” Rivers said of Griffin, via Gary Washburn of The Boston Globe. “That’s happened many times in my career, so I don’t make a big deal of that. You guys do, but I don’t at all. I’ve had some guys, even some guys I’m very close to — most trades and departures don’t go very well, for the record. They just don’t. I can cite you 100 of them, Kendrick Perkins [in Boston], who was like my son. Nah, they don’t go well. “We all come back eventually.”

Much like Griffin, Perkins was also very close to Rivers during their time together with the Boston Celtics. Perkins was traded midseason as well (back in 2011), and he too must have felt terrible about being offloaded by a team he had shown so much loyalty.

As Rivers explains, it is only natural for a traded player to feel upset for being moved, and at times, the blame is put on the coach. Perhaps some players feel that it was his (former) coach that pulled the trigger on the deal, or that he didn't fight for him enough. Either way, someone has to be on the receiving end of one's pain.

For Blake Griffin, it appears that he is still holding Doc Rivers somewhat accountable for the trade, and he's currently not ready to bury the hatchet just yet. Give it another year or two, maybe?
