RIP RPI

"The NCAA Evaluation Tool, which will be known as the NET, relies on game results, strength of schedule, game location, scoring margin, net offensive and defensive efficiency, and the quality of wins and losses. To make sense of team performance data, late-season games (including from the NCAA tournament) were used as test sets to develop a ranking model leveraging machine learning techniques."

"To ensure fairness, certain types of data were omitted from the model. Of key importance, game date and order were omitted to give equal importance to both early and late-season games. In addition, a cap of 10 points was applied to the winning margin to prevent rankings from encouraging unsportsmanlike play, such as needlessly running up the score in a game where the outcome was certain."

Nice wordplay! This is good...scoring margin should be used in any rating scheme. A team that loses by an average of 30 points to a certain group of teams should not be rated the same as another team that loses by 5 points to that same set of teams.

We rarely lose football games by excessive amounts although we have lost by 2 touchdowns or more at times. Other sports not sure.  Suppose we lose to South Carolina this season by 20 points or more . What does that do for us versus losing by 5 or 6 points on the road.

...They won't stop tweaking until they can guarantee that ALL at-large bids are received by Power5 schools. That's my take

I donít think so. If the new rating adds in margin of victory/loss, it reduces impact of SOS...which previously was a lock for P5 teams.

I really don't think this changes all that much. But I guess we'll have to wait until March to find out.
