Counting down eight classic coaching rivalries of the past:
8. Jerry Tarkanian vs. Lute Olson: Tarkanian called Olson "Midnight Lute" for his recruiting practices and laid it on Olson in a Sports Illustrated article, according to the Tucson Citizen.
7.Gene Keady vs. Bob Knight: The two intense coaches had years of passionate contests when Purdue battled Indiana for supremacy in a basketball-crazed state. Knight's chair-tossing incident came against Purdue.
6. Bruce Pearl vs. Jimmy Collins: Pearl turned in Illinois on a recruiting violation when Collins was an Illinois assistant. As a result, the two did not shake hands after games when Collins became head coach at Illinois (Chicago) and Pearl was head coach of Wisconsin (Milwaukee).
5. Rick Barnes vs. Dean Smith: Barnes, then head coach of Clemson, had a heated sideline exchange with Smith during an ACC tournament game in 1995 after the North Carolina coach pointed at one of Clemson's player following a hard foul.
4. Billy Donovan vs. Eddie Fogler: In 1998, Fogler, then South Carolina's head coach, made a reference to a Southeastern Conference school involved in unethical recruiting. He obviously meant Florida, coached by Donovan. Donovan called Fogler a coward for not naming the school.
3. Pete Gillen vs. Bob Huggins: Huggins, then head coach at Cincinnati, and Gillen, Xavier's head coach, exchanged heated insults during a game in 1994. Huggins refused to shake Gillen's hand afterward in this intense Cincinnati rivalry.
2. Billy Tubbs vs. Norm Stewart: Stewart refused to shake hands with Tubbs after Missouri beat Tubbs' Oklahoma team in 1986. Earlier in the season, Tubbs had called Stewart "Francis the talking horse." Tubbs later "apologized" for not calling him a mule rather than a horse.
1. John Chaney vs. John Calipari: Temple coach Chaney charged at Massachusetts coach Calipari during Caliprari's postgame press conference in 1994. Chaney threatened to kill Calipari, still a YouTube favorite.
