I believe SC called the time out so they can advance the ball to the front court. If only MO. called the time out, the ball would have been inbounded in the back court. Not that it matters, but only a lob tip would be allowed as a score with .01 left on the clock. I would have had SC players try their best to draw a foul(theatrics are needed.)
On the last play for MO, notice the big for MO #0, stood out by the 3 point line, hoping to draw Boston out to her and away from the lane. Boston, watched her, and then got back to the paint when she saw what was happening. It might have been a second too late to stop the lay up. The Big for MO, that I mentioned above, played for SC last year. I dont believe she has taken a 3 pointer this year, and maybe only one 3 pointer last year. Good play calling by the MO. coach.
