I'm not sure what you want the average of? Post Up FG%, percent of the time a team scores when they attempt to score on a Post Up or points per possession on that type of play?What is the NCAA average?
But don't worry, I don't know how to calculate it because not all teams us Post Ups the same number of times per game. Rutgers uses Post Ups 9.6 percent of the time, Iowas 12.4 percent of the time, Tennessee 15 percent of the time and so on.
