Funnily, on his pod Bill Simmons said starting Grant in the second half was a brilliant coaching move by Udoka because when he brought in Rob later it meant Bam never had a chance to come off the court for a rest in the third quarter.In a post-game interview last night Grant said that he had no expectation of starting the second half, and did so only because Rob was in the bathroom at that moment. Timelord being Timelord.
So maybe Ime just asked Rob if he had to go.
