The Memphis Grizzlies have been struggling recently and yes J.B. Bickerstaff deserves a lot of the blame but despite that, he is nowhere near being on the hot seat.
Last season he took over after David Fizdale had been fired and the team was in full-blown tank mode. Mike Conley was out for the season and they had no chance at making the playoffs.
Fizdale and Marc Gasol had their infamous feud and the team chose Gasol. Fizdale may have eventually been on the way out anyway but they opted to keep their longtime center happy rather than keeping Fizdale as their head coach.
