I didn't remember Merchant coming on the court for Johnson. I figured that the ref calling a stoppage in play for Johnson's injury was enough for a substitution, but I didn't know the rule.
I just went back and watched the 2nd half of the BTN "Student U" video, and Merchant wandered a couple of feet onto the court and then went back and stood in front of her bench, feet firmly out of play. Johnson's teammates came back to check on her and huddle around while she took a really long time to re-tie both of her shoes, but in the bit that was shown on the video (a replay of the injury was being shown) there were no Spartan staffers on the floor.
The announcers didn't know why Borseth was so upset. "Borseth is animated about something....not particularly sure what he's worried about." and finally made the assumption that he was arguing about Johnson being allowed to stay in. One of the students said, "I guess...technically she must be required to come out...".
Merchant was warned about coming out of her box in the 2nd half when one ref called a jump ball and the other called a foul (on Bell?). The 3rd ref talked to her and pointed her back to the box, and that was the end of it.
Wow. Boylan was really wide open on that last attempt. I thought when watching the game, that she was starting to pass or dribble to her right and then realized that she had the shot and took it a bit off balance. On the video I only saw a slight hesitation.
