Is that I bet a part of why Nolan hired him is that he didn't think Norv would leave to become a head coach in a year or 3.
He had to be thinking that this guy in his 50's who had been an abject failure in his 2 previous head coaching trials would probably never get another job.
He had the most qualified candidate and a guy who wasn't a threat to take his job or any other job. Best case scenario.
