Blake Griffin -- RIPS Donald Sterling ... 'He Was Like A Weird Uncle'

Blake Griffin says he's THRILLED the Clips are finally rid of Donald Sterling -- saying the guy was "like a weird uncle" who was clearly "off his rocker."

Griffin just spilled his guts about his former boss on The Players Tribune -- saying his relationship with Sterling was bizarre from day 1 ... when the old man tried to hook him up with two women at a Malibu beach party who were likely paid escorts.

"Two blonde models showed up on either side of me. They had clearly been hired for the event. I knew this because they were wearing size XXXX-L Clippers T-shirts tied at the stomach. I looked at Sterling. He had a big dumb grin on his face. I looked at one of the girls, as if to say, “Uhhh, you don’t have to do this.” She looked back: “Uhhh, yes I do."

In the article, Griffin also talks about how he felt the first time he heard the infamous Sterling audio recording -- saying:

"It was shocking to actually hear what he said, but not really that surprising to me."

There's more about Sterling ... here are some of the highlights:

-- "The guy was off his rocker."
-- "He kind of sounds like a combination of Walter Matthau and Michael Jackson."
-- "[Steve Ballmer] is a good dude. He’s like a cool dad who gives you candy. Donald was like a weird uncle"

Griffin concluded his tell-all with this nugget:

"Someone asked me the other day if I’m mad that he made out with $2 billion for selling the team. Maybe a little bit. But in the end, I’m just happy he’s gone."
