Maybe he wasn't as responsible as most assumed for that season? In other words, put Kenny Atkinson or another qualified coach in that position at that time and maybe the same thing happens?
Don't know, but it's possible if not likely that 99% of the success was simply that group of players coming together for the first time in that season and fitting pretty well.
Mike got coach of the year, but there really wasn't anything that stood out to me as him doing anything out of the ordinary "great". Sure the timing in Sacramento was big to break the playoff streak, but nothing that he was doing looked like it couldn't have been done by some others
