I thought this was interesting... I was told recently that all players have an app on their iphone where they have to "check-in" when they get to class. One of the bball staff monitors to make sure they are checking in to all of their classes...

Evidentially the app also lets them see who is "out" later than they should be... not 100% about this part, but was told absolutely it tracks the player class attendance.

Just hadn't head this before and thought it was pretty cool..
