He is asking Joe to play out of position. He didn't bring in a real 4th guard, so Joe now had to play almost a full game outside his natural position. Also, doesn't he have asthma, too?
He also screamed at Joe on the court, on TV.
He trashed him in the presser.
Again, I can't believe I'm the poster saying this, I feel bad for Joe.
Also, combined with the Jesse comments and what he did with Benny, I mean, it's embarrassing. Or at least it should be considered embarrassing.
But, when there are no consequences, who cares?
