DiVincenzo was dubbed the "Big Ragu" by sportscaster Gus Johnson following his last-second tip in a game on January 29, 2017, which gave Villanova the win against the University of Virginia. The nickname was given to him ostensibly due to his Italian heritage and his red hair. On April 19, 2018, DiVincenzo announced he would declare for the 2018 NBA draft without hiring an agent, thereby leaving open the possibility of a return to Villanova. On May 29, 2018, DiVincenzo announced he would remain in the draft and hire an agent, forgoing his final two years of eligibility at Villanova.
