There were other factors at play, of course, but you cannot deny that the Suns owner Robert Sarver’s pattern of coach firings based on recent won-loss streaks.
Ever since Mike D’Antoni left of his own accord in 2008, every full time coach of the Suns has been fired mid-season in a reactionary move to recent losses.
The Suns were an abysmal 13-28 in the first half-season after Steve Nash was traded to the Lakers for future first round picks when Gentry was suddenly fired/quit on a Wednesday night immediately following their 28th loss in 41 games.
