Due to NCAA eligibility rules that prohibited freshmen from playing varsity sports, Heyman played his first year at then racially segregated Duke with the freshman team, which compiled a record of 10–5, including three victories over the Tar Heels. During one of the Duke-North Carolina freshman games, North Carolina freshman Dieter Krause attacked Heyman, leading to a melee where the two coaches had to be restrained from attacking each other. Heyman needed five stitches after the attack. During his sophomore season, Heyman starred for the varsity team, and North Carolina and Duke again were at each other's throats. On February 4, 1961, the Duke and North Carolina freshman teams had played the first game of the double header. There were multiple fights during the game, and North Carolina had finished the game with only three players on the floor (five North Carolina players had fouled out, and three more had been ejected for fighting). During the varsity game that night, Heyman was involved in two incidents, where he first pushed over a fan who he thought was attacking him, and then in the closing minutes of the game, while trying to protect a slim Duke lead, Heyman committed a hard foul against future Hall of Fame coach
Larry Brown who was attempting to drive to the hoop. Brown threw the ball and then a punch at Heyman, touching off a general melee, which saw future basketball executive
Donnie Walsh, then a substitute player for North Carolina, also attack Heyman. The melee lasted about ten minutes, and despite Heyman being ejected for fighting, his 36 points had given Duke the victory, 81–77. In 1962, Heyman's junior year, he again had a great year (scoring 25.3 points per game, and averaging over 11 rebounds per game) but Duke failed to make the post season, being upset by the
Clemson Tigers in the
ACC Tournament semi-final. Heyman was once again voted to the All-ACC Basketball first team, and the AP and UPI Second Team All-American squad. ==Professional career==
