The Role of Wins Above Bubble (WAB) in Selection Decisions
As the NCAA Tournament approaches, the selection committee utilizes various metrics to evaluate teams, among which Wins Above Bubble (WAB) has emerged as a significant tool. Introduced in the previous season, WAB measures a team's performance against its schedule compared to what an average bubble team would achieve. This metric is particularly valuable as it remains unaffected by victory margins, focusing solely on the accomplishments of teams. Dan Gavitt, NCAA senior vice president of basketball, noted that the selection of at-large teams correlates more closely with WAB rankings than with the NET rankings, which have traditionally been a staple in selection discussions.
How WAB Functions
WAB assigns a score based on the strength of opponents and game locations, providing a 0-1 score for each game. For example, a victory against a highly ranked opponent yields significant WAB points, while losses incur minimal penalties. This scoring system allows for a nuanced comparison between teams with varying schedules. For instance, Miami University, despite having no losses, has a modest WAB score due to the weaker strength of its opponents, while teams like Auburn gain substantial WAB points from challenging victories.
Miami University's Tournament Prospects
Miami University, currently undefeated with a WAB score of approximately 2.15, is navigating the NCAA Tournament bubble. The RedHawks' performance has garnered attention, but their lack of Quad 1 games raises concerns among analysts. Winning the Mid-American Conference (MAC) Tournament is crucial for Miami, as it guarantees a spot in the NCAA Tournament. However, if they do not secure the automatic bid, their WAB score will be pivotal in determining their at-large chances.
Selection Scenarios for Miami
Miami's path to the NCAA Tournament involves several scenarios based on their performance in the upcoming MAC Tournament. Winning the tournament ensures a secure spot, regardless of their regular-season performance. Conversely, losing in the tournament could significantly impact their WAB ranking. If Miami finishes the regular season undefeated but loses in the MAC Tournament, they could still maintain a favorable WAB ranking, though any loss against MAC opponents would carry a heavy penalty.
In a more precarious situation, if Miami were to lose both a regular-season game and a MAC Tournament game, their chances of selection would diminish considerably. A three-loss scenario would likely place them outside the bubble, as their overall resume would not support an at-large bid.
Official Statements & Responses
Gavitt emphasized the importance of WAB in the selection process, stating, "The hardest decisions the committee has to make are probably those at the bottom of the at-large selection." He noted that WAB helps the committee compare teams from different leagues and schedule strengths more effectively.
Conflicting Reports & Gaps
While WAB has gained traction as a selection metric, there remains some debate about its weight compared to other metrics like NET. Critics argue that reliance on a single metric could oversimplify the selection process, which involves multiple factors beyond just win-loss records.

- “I think fans would be probably pretty surprised that the selection of the at-large teams was probably more highly correlated to a team's WAB ranking than it was their NET ranking,” — Dan Gavitt, NCAA Senior Vice President of Basketball
- “But at the same time, we want to make sure people are not hyper-focused or overly focused on that, because it's really just one component.” — Dan Gavitt, NCAA Senior Vice President of Basketball
As the NCAA Tournament approaches, the significance of WAB in evaluating teams continues to evolve, shaping the narratives surrounding potential selections and seeding.
