Q: What about this "good wins" or "bonus points" criteria? Isn't this just a subjective fudge factor?
The so-called bonus for "good wins," instituted for the 2003 tournament, is not subjective. Teams get bonus percentage points added to their RPI for defeating teams that finish the season in the Top 15 of RPI. For 2006-07, the bonus criterion was altered to give points only for a road win, as opposed to the old system, under which home and neutral-site wins also counted, albeit less than road wins. This further limits the importance of this factor. The amount of bonus points awarded has not been made public by the NCAA, but it is a fixed and finite amount.
Because the committee chooses to keep the amount of the bonus secret, it opens itself up to people believing its used as a fudge factor. You'll have to trust us that it's not.
