From 1963-67 he was known as "Big D," "Captain Stuff" and "Captain Hook" at Akron U, where he was an outstanding basketball and track athlete. As a freshman, Williams became a starter on the 1963-64 team, which gained national prominence by finishing as national college division runner-up to Evansville. That season began a string of three consecutive Ohio Conference titles and Mideast Regional crowns. The 1965-66 team finished third in the national finals. And if the 1966-67 team had not run into Earl "The Pearl" Monroe in the Mideast Regional championship, Don and company probably would have grabbed the only title which evaded them in his four seasons - the national championship. As a senior the 6-5 talent was voted the Athlete of the Year while scoring 450 points and grabbing 315 rebounds to give him career totals of 1,445 points, 1,218 rebounds. As a four-year letterman, Don helped the Zip thinclads capture 32 of 37 meets including the OC Championships in 1965 and '66.
