I said this in another comment below but:
As a therapist, I'm curious if the team picked someone out for him (my suspicion) or allowed him to find his own therapist.
One of the first things we learn as therapists is that training and modality isn't as important as the relationship btw. therapist and client. If Kai felt forced to go and couldn't even choose who he saw, it's no wonder he felt like it wasn't helping.
this is what the NBA was like in 2005
