The 6-11 Yugoslavian Olympian center who played like a guard was a three-time first-team All-WAC selection and an All-American. Like Ainge and Fredette, the 22,700-seat BYU Marriott Center attendance figures testify of his popularity and skill, reflected in the quote after it was opened in 1971: "(former coach) Stan Watts built it, Marriott paid for it, and Cosic filled it."

Cosic is listed in the 1997 book "100 Greatest Basketball Players of All Time," Cosic was the fourth European ever selected at the time in the NBA Draft
