Sure looked like it.
With about 3 minutes left, JOB pulled Jermaine and JO was angry walking off the court. The coach grabbed his arm as he walked by to say, "What's the problem?" but JO just yanked away and kept walking.
My take on it is that JOB wanted to say, "Look, you're still injured. I'm not gonna keep you in when things heat up at the end."
JO, for his part, obviously wanted to be in at the end to affect the outcome. Another loss is on the books when he plays 25+ minutes, but he really didn't get a chance at the end to gain a victory.
However, I'm glad JOB didn't buckle and kept him out for good. If our coach keeps up that kind of discipline, he will continue to command respect and it will be good for everyone in the long term.
