HONOLULU (AP) — Bob Nash was fired as coach of the University of Hawaii’s men’s basketball team on Monday after posting a 34-56 record over three seasons. ‘‘This was a very tough decision,’’ athletic director Jim Donovan said in a statement. ‘‘No person has shown more dedication to UH basketball than Bob Nash.’’ Nash was a member of the ‘‘Fabulous Five,’’ a group of UH basketball players during the 1970-71 and 1971-72 seasons that led the team to a 47-8 record. They made the postseason twice, including the school’s first NCAA tournament appearance. He became head coach in 2007 after 23 seasons as an assistant coach, replacing Riley Wallace, who retired after 20 years at Hawaii and making his mark as the school’s winningest coach with 334 victories. As the program’s 18th head coach, however, Nash was unable to steer his teams onto a consistently victorious path. His first season ended with an 11-19 mark, including upset wins over New Mexico State and Utah State.
