<Tr> <Td_colspan="2"> 1932, 1975, 1980, 1995, 2002, 2010 </Td> </Tr> <P> The Maryland Terrapins men's basketball team represents the University of Maryland in National Collegiate Athletic Association Division I competition . Maryland, a founding member of the Atlantic Coast Conference (ACC), left the ACC in 2014 to join the Big Ten Conference . </P> <P> Gary Williams, who coached the Terrapins from 1989 to 2011, led the program to its greatest success, including two consecutive Final Fours, which culminated in the 2002 NCAA National Championship . Under Williams, Maryland appeared in eleven straight NCAA Tournaments from 1994 to 2004 . He retired in May 2011 and was replaced by former Texas A&M coach Mark Turgeon . </P> <P> The Terrapins played in what many consider to be the greatest Atlantic Coast Conference game in history--and one of the greatest college basketball games ever--the championship of the 1974 ACC Men's Basketball Tournament, in which they lost 103--100 in overtime to eventual national champion North Carolina State . The game was instrumental in forcing the expansion of the NCAA Men's Division I Basketball Championship, thus allowing for at - large bids and the inclusion of more than one team per conference . That Maryland team, with six future NBA draft picks, is considered by many to be the greatest team not to have participated in the NCAA tournament . </P>
