I'm guessing the call during timeout was something like "Give it to Hudson to try to drive it inside. If it isn't there, let's kick it over to Kevaughn on the perimeter to drive to the basket if it is open, if not, take the perimeter shot." In theory with the defense collapsing on Hudson driving to the basket, Kevaughn was likely to be open for at least a mid-range jumper
The breakdown happened when Hudson slipped, and the ball slowly trickled over to KJ, who did as he was coached, rather than adjust (take the scorer role) with the clock winding down. This allowed the defense to back away from Hudson and reset closer to the basket. It further broke down when Kevaughn didn't recognize that too much time was gone to try to drive it inside, even if it had been there. At most he had time to take a step or two inside, but definitely not to get it to the hoop, which was guarded by their trees anyway.
The play call wasn't a bad one, the execution was horrible. I can't really blame Hudson for slipping, things like that happen. I can't blame KJ for trying to get the play back on track, even though a more experienced KJ would either take the perimeter shot or step in for a midrange jumper. I do blame Kevaughn for not recognizing that there wasn't time to drive the ball all the way to the basket, and not taking either a perimeter shot, or, better, to dribble in one or two steps and create space for a 12-15 footer.
