Kentucky is the fifth defending champion to miss the NCAA Tournament since the field expanded in the 1984-85 season. Here are the others.

2010

North Carolina: Tyler Hansbrough led the Tar Heels to a national championship the year before, and UNC started its title defense with a No. 6 national ranking. The Heels stumbled in conference play, going 5-11 in the ACC before heading off to the NIT with a 16-16 record. They made a run at the title but fell to Dayton in the finals at Madison Square Garden.

2008

Florida: No one expected much from the Gators after Joakim Noah and company won back-to-back titles and left early for the NBA. Florida started the season unranked in the Associated Press poll. Nick Calathes led the team to an 8-8 SEC record and a spot in the NIT. The Gators were eliminated by UMass in the semifinals at the Garden.

1989

Kansas: Larry Brown coached Danny and the Miracles to a championship in 1988, but Brown and Manning had jobs in the NBA by the time the NCAA hit Kansas with a tournament ban later that year. New coach Roy Williams led the Jayhawks to a 19-12 record, and their season ended with a loss to Kansas State in the first round of the Big 8 Tournament.

1987

Louisville: Pervis Ellison returned and the Cardinals started their title defense with high hopes and a No. 2 national ranking. But those hopes faded with three losses — to Northeastern, Washington and Texas — in three consecutive days to start the season. Crum's bunch wasn't ranked again that season, which ended with an 18-14 record and a loss to Memphis State in Metro Conference Tournament.
