If you recall, I fought for the removal of bonus points in the RPI system in 2012. Since that time, bonus points are no longer awarded for Top XX wins in conference ... which solved the bigger problem with the RPI bonus system. If they removed the bonus for OOC wins, you would have an even bigger problem in scheduling the elite conference schools in OOC games.
The real problem is the RPI system itself and people believing too much in the rankings that it produces.
