Why Does RPI Matter?
Kelly Kulina: Your Link to the Colleges
Why does the RPI matter? To get into the NCAA postseason, teams will either need to win their conference championship or earn an “at-large” bid. These at-large bids are awarded by an NCAA committee to teams that win a convincing number of games during the regular season. In the case of team sports, RPI is used to determine whether or not a “bubble” team should be given or denied an at-large bid to the tournament. Teams with wins over tough competition typically get the nod over teams with the same number of wins over easier competition.For those of you who aren’t college basketball fans, Relative Power Index (RPI) is a measure of a team’s strength of schedule. So, teams are credited for playing a tougher schedule and penalized for playing a softer schedule.
To calculate a team’s RPI, the NCAA uses the following formula:
(0.25 * team winning percentage) + (0.50 * opponents’ winning percentage) + (0.25 * opponents’ opponents’ winning percentage)
As you can see, winning is only 25% of the total index, with much more emphasis being placed on teams’ opponents.
As with anything involved with the postseason, the RPI and its role in postseason selection does not come without controversy. Critics of the RPI point out that it compounds the disadvantage cold weather teams face against warm weather teams. Since they must spend the first three weeks of the season on the road, many cold weather teams will start with a losing record and play against other teams in their conference with losing records. This creates the compounding effect causing the RPI disadvantage. In fact, many lower tier teams in warm weather conferences will get an at-large nod over upper tier teams from cold weather conferences. If you take a look at the past few years’ College World Series participants and winners, you’ll see a major disparity between cold weather teams and warm weather teams.
This past November, Greg Van Zant, Head Coach at West Virginia University, proposed a change in the calculation of RPI. Rather than counting all wins equal, he suggested using an “adjusted winning percentage,” which awards 1.0 wins on a neutral site, 1.25 wins on the road and 0.833 wins at home. College basketball is currently using something similar, although they award 1.4 wins on the road and 0.6 wins at home. While this is still a while away from being presented formally to the Division I baseball committee, I’m looking forward to seeing how it is received by other coaches and the NCAA.
There’s no doubt in my mind that northern teams could use a helping hand when it comes to staying competitive nationally. At the same time, one thing won’t change: you still need to win the majority of your games!
