Ian Begley of SNY got in touch with the man who knows the relationship between Steve Nash and Kevin Durant the best, Bruce Fraser. He’s both a close friend of Nash, and worked at Golden State when Durant and Nash were together for three years, Nash as a player development consultant.
As Begley writes...
He has a close relationship with Durant, one that was solidified during his five-year tenure as a Warriors consultant. When Durant joined Golden State, he was transitioning into the middle stages of his career.
