At D1, promises don't carry near enough weight. As zbrent said, they are probably somewhere on the order of a campus visit. IMO, promises should not be worth a fixed value, but should be a multiplier to other efforts. If you promise a start/significant minutes, there should be a 10-15% multiplier to all other recruiting efforts, or something along those lines. While starts/minutes should be worth more than they are currently, we need to balance things so that promises don't unduly overwhelm all other efforts. Do that, and it becomes too much of a cheap magic bullet.
