He clearly does not like Cal and did not like his time at UK. That's OK, every coach has some players who dislike him and not every player is gonna like it here.
But I don't understand why Wenyen feels this need to periodically remind us once every few months. Let. It. Go. I could understand it better if his story had an unhappy ending, but instead it had a a happy one, he DID end up making the NBA. Albeit not the way he wanted, he had to work his way up in the G-League for a couple years instead of taking the direct route, but he STILL eventually made it.
Not sure why he can't just enjoy that success without repeatedly reminding us of his bitterness over past issues.
