In case the tweet disappears, here's what it said:
Pete: "Juice, I have no doubt that you are better than me, but I'm not there anymore brother. Reach out to Teena Murray, the Kings decided a couple years ago that she was better suited to guide their sports medicine & performance departments. Continued success to you my man." (In answer to a question from someone wanting Pete's help in getting on the Kings training staff...)
Pete: "All good Ross, I left amicably and on my own accord. Essentially I decided I wasn't going to work under a person less qualified than myself to do the job I did successfully for a number of years. It was time for me to move on. I did not want to leave, but I also have no regrets." (In response to a question from Ross, who wanted to know why Pete left...)
I don't think I've ever seen Pete make comments like that publicly before.
My personal two cents? I'm pretty sure I can guess who forced Pete out and it wasn't Vivek or Vlade.
