Under coaches Floyd (1995–98) and Larry Eustachy (1998–2003), Iowa State achieved even greater success.  Floyd took the Cyclones to the Sweet Sixteen in 1997 and Eustachy led ISU to two consecutive Big 12 Conference regular season conference titles in 1999-2000 and 2000–01, plus the conference tournament title in 2000.  Seeded No. 2 in the 2000 NCAA tournament, Eustachy and the Cyclones defeated UCLA in the Sweet Sixteen before falling to Michigan State University, the eventual NCAA Champion, in the regional finals by a score of 75-64 (the differential representing the Michigan State Spartans narrowest margin of victory in the tournament).  Standout Marcus Fizer and Jamaal Tinsley were scoring leaders for the Cyclones who finished the season 32-5.  Tinsley returned to lead the Cyclones the following year with another conference title and No. 2 seed, but ISU finished the season with a 25-6 overall record after a stunning loss to No. 15 seed Hampton University in the first round.
