Four teams in the top 10 of ESPN’s Basketball Power Index lost last weekend, but the impact on the BPI rankings heading into this week’s major conference tournaments was minimal. The differences between the 0-to-100 BPI ratings of top teams meant that the drop in a team’s BPI after a loss often wasn’t enough to alter the rankings.
BPI No. 1 Arizona fell 64-57 at Oregon on Saturday and lost 0.7 in its BPI rating. But the Wildcats had enough of a cushion over No. 2 Florida that they maintained the hold on the top spot. Similarly, No. 9 Wisconsin, which lost at Nebraska on Sunday, maintained its ranking despite a 1.0 drop in BPI.
Kansas falls after Shockers’ victory
A 92-86 loss at West Virginia brought Kansas’ BPI rating down 0.7, and the Jayhawks kept their No. 3 BPI ranking after Saturday’s games.
After Wichita State won the Missouri Valley Conference tournament championship game Sunday, the Shockers got a bump of 0.2 in their BPI – a small bump, but large enough for Wichita State to move from No. 4 to No. 3 in the rankings, leapfrogging Kansas. The Jayhawks, who have the toughest schedule among BPI Top 15 teams, are No. 3 in the NCAA’s RPI rankings but fell from eighth to 10th in the weekly Associated Press poll.
Of the BPI Top 10 teams that lost, only Virginia (a 75-69 overtime loser at Maryland on Sunday) dropped in the rankings immediately after the defeat, from No. 7 to No. 8.
Pac-12 climber and faller
Oregon, in its BPI rating, gained less than Arizona lost after their game Saturday but climbed four spots in the rankings Sunday to No. 16. The Ducks have won seven games in a row (earning a BPI Game Score of at least 90 in five of them) and exceeded a 90 Game Score in its loss at Arizona on Feb. 6. The NCAA’s RPI has Oregon at No. 25, and the Ducks have the third-most votes among teams finishing out of the top 25 in the AP poll.
The biggest faller in BPI rankings among the Top 50 was UCLA. The Bruins lost 73-55 at No. 175 Washington State on Saturday and fell from 11th to 21st. UCLA earned a Game Score of 10.6 against Washington State, 10 points lower than any other game score for a team currently ranked in the BPI Top 25.
In the eye of the beholder
Michigan is eighth in the AP poll, ninth in RPI and a No. 2 seed in Joe Lunardi’s Bracketology. In BPI, however, Michigan is 22nd. Of the Wolverines’ seven losses, four have been by at least 10 points; of their wins, seven have been by five points or fewer. Also, Michigan is 8-1 with an 88.7 BPI against opponents missing at least one of their top five players (in terms of minutes per game), and BPI de-weights those games.
Louisville rose from 11th to fifth in the AP poll, but the Cardinals are a projected No. 4 seed in Bracketology and are 22nd in RPI. BPI ranks the Cardinals fifth. All five of Louisville’s losses have been to BPI Top 50 teams and have been by an average of six points, whereas its five wins against Top-50 opponents have come by an average of 13.4 points.
