If UT had played two Division 2 schools instead of Kennesaw St and Presbyterian their RPI would have only shown 18 wins on selection Sunday but their RPI would have been higher. Those 2 teams were both sub 300 and counted heavily against UT. Play 2 Div 2 schools instead and there is no hit to the RPI. The committee has shown that 20 wins is not that important a plateau anymore. (good or bad).
The biggest thing is if this type of thing becomes prevalent in all conferences. If other conferences start doing what the MWC did and schedule Div 2 instead of lower Div 1 schools, then the SEC will have to do so as well or the conferences' SOS will fall even further behind than it is now.
