Teams with No. 1 schedule strength rankings can usually look forward to an NCAA tournament invitation

Vanderbilt had best end of regular season overall schedule strength rank but lost in first round of NCAA tournament

The Vanderbilt Commodores won top honors for the best overall schedule strength at the end of the 2017 regular season through games of Selection Sunday. In addition, Vandy had the No. 3 rank of opponents' RPI played, along with the No. 1 opponents' won-lost record of 676-401 (.6277) in the regular season, which are both alternate ways of determining schedule strength. Louisville had the No. 1 rank of opponents' RPI played. The Commodores received an at-large bid to the 2017 NCAA tournament with a No. 9 seed but lost to No. 8 seed Northwestern 68-66 in the first round. Since 1991, 22 of the 27 teams holding the No. 1 schedule strength rank at the end of the regular season were in the NCAA tournament, and 23 of those 27 teams were in post-season play. (Georgia, in 2003, was ineligible.) However, having the No. 1 schedule strength does not guarantee success in the NCAA tournament. In 7 of the last 17 seasons, the team holding top schedule strength honors has lost in the first round of the NCAA tournament. In the 10 years prior to that, not a single team with the No. 1 schedule strength that made the NCAA tournament lost in the first round, although 3 of those teams did not make the NCAA tournament. The best NCAA tournament performance for a team with the best regular-season schedule strength since 1991 was North Carolina in 1997, which lost in the national semifinals to eventual national champion Arizona. Notre Dame had the best regular-season schedule strength in 1992 with a 14-14 record and finished second in the NIT.

The Division I record shown below is for the final, regular season.
