I remember in the offseason he talked about using a shot tracking tool that tracked how much each player practiced shooting. And apparently he really held them accountable and they could see each others result. I don't know how many teams use it, but Pope said a lot of teams are using it, and BYU had put up more shots than any team in the country that used it during the offseason.
"Pope’s practices do have some unique features. There is a big white board titled, “BYU Cougars Winner’s Board” which keeps track of the best performances during drills. He uses Shot Tracker to log the player’s shooting numbers. There are video screens to playback certain parts of practice and Pope has a microphone so he can be heard no matter where the players are working. He has the option of practicing in the cavernous Marriott Center or the smaller Annex next door."
