Ganakas taught and coached basketball at
East Lansing High School, where he won the 1958 State of Michigan High School Championship, posting an undefeated season. In 1964 he became the Coordinator of the Ralph Young Fund, MSU's athletic fund-raising organization. A passion for sports led him back to the world of basketball when Coach John Benington hired him as his MSU assistant basketball coach in 1966. Three years later, with the sudden death of Coach Benington, Ganakas became the head basketball coach for the Spartans, from 1969 to 1976, compiling an 89–84 (.514) record over 7 seasons. Controversially, a number of black players walked out on coach Ganakas before a key Big Ten game on January 4, 1975, against
Indiana. Ganakas elected to start Jeff Tropf, who was white, 10 black players, led by captain
Lindsay Hairston, walked out of the team meeting, returned for the game but were then suspended by Ganakas. Michigan State lost the game 107-55 with a patchwork roster that included junior varsity players. Tropf led the team with 21 points. The players would meet with Ganakas the next day, were reinstated after apologizing, and then defeated
Ohio State 88-84 the next day. Tropf would transfer to
Central Michigan at the end of the season. Ganakas was dismissed after the conclusion of the next season on March 16, 1976, but stayed with Michigan State as an Assistant Athletic Director through 1998 and then as an advisor to Spartan Head Coach
Tom Izzo through 2000. Ganakas also spent his post-coaching years as a radio
analyst on the Spartan Sports Network. He was an active member of the Detroit Sports Broadcasters Association. In 2002, Ganakas became the sixth recipient of the Men's Basketball Distinguished Alumnus Award. The Michigan State team MVP award is named in his honor. ==Personal life and death==
