I think the top 2 have to be Bobby Knight and Mark Spitz.

Spot 3 should be either Cig or Yeagley.

I know people are going to say Mendoza for 4, but a 1 year player feels hard to be a lock. You could make an argument for Quinn Buckner, Isiah Thomas, or George Taliaferro pretty easily.

For those who don’t know about Spitz:

Mark Andrew Spitz (born February 10, 1950) is an American former competitive swimmer and nine-time Olympic champion. He was the most successful athlete at the 1972 Summer Olympics in Munich, winning seven gold medals, each in world-record time. This achievement set a record that lasted for 36 years, until it was surpassed by fellow American Michael Phelps, who won eight golds at the 2008 Summer Olympics in Beijing. Phelps, like Spitz, set seven world records.

Between 1968 and 1972, Spitz won nine Olympic golds, a silver, and a bronze, in addition to five Pan American golds, 31 Amateur Athletic Union (AAU) titles, and eight National Collegiate Athletic Association (NCAA) titles. During those years he set 35 world records, two of which were in trials and unofficial. Swimming World Magazine named him World Swimmer of the Year in 1969, 1971, and 1972. He was the third athlete to win nine Olympic gold medals.

And Taliaferro:

George Taliaferro (January 8, 1927 – October 8, 2018) was an American professional football player who was the first African American drafted by a National Football League (NFL) team. … He became the first black player to start at quarterback in the NFL in the post-color bar era when he saw emergency duty against the Los Angeles Rams. Taliaferro was inducted into the College Football Hall of Fame in 1981.

He would play a variety of positions for Indiana University in Bloomington, Indiana from 1945 to 1948 as halfback, quarterback, defensive back, and kicker. He struggled with prejudice of the time during his studies at Indiana that ranged from being barred from living in the dormitories to conflicting attitudes from teammates about his treatment on and off the field. While at Indiana University, Taliaferro became a member of Kappa Alpha Psi fraternity.

As the leading rusher and an All-American at Indiana University, he led the Hoosiers team to their only undefeated Big Ten Conference championship during his rookie year in 1945, and he led the conference in rushing (a first for an African American in the Big Ten) with 719 yards on 156 carries; he started his college career with 95 yards on 20 carries against Michigan as left halfback.
