Did you notice Ray Acosta runs up and down the court "out of bounds?" Marlin definitely 'had position'! He may have had one foot on the court but the ref was running up the sideline, 'out of bounds'. I noticed the ref on the other side of the court did not do this. He stayed on the court.
After Marlin took the 'charge', the head referee took charge, called a 'conference' and the call was "reduced" to a coach's box warning. I didn't know they had that in basketball. Maybe it was a bench warning. Anyway, I think after the next media timeout (8 min. mark of the first half?) the officials convened again. When play resumed the officials had switched sides and Acosta was on the media side of the court and the other official was on the team side. I think the head official helped that young official out of what could have been a very tense situation. Veteran move on his part. Acosta was back on the team side of the court in the second half. I thought he would have stayed on the side opposite the team benches. It all worked out. No more incidences.
