Walker joined Coach Russ Beichly and The University of Akron in the 1942 season fresh out of East High. While at East, he was a member of the famous "Cinderella Kids" that annexed the city crown. At the end of the 1944 season, Walker got the call from Uncle Sam and spent 2-1/2 years in the Army. Bobby re-entered UA and played on the 1947-50 teams. Relegated to the sixth man in the 1947 opener against Baldwin-Wallace, Walker entered the game in the fourth quarter, hit five of six shots, scored 12 points to insure a 63-54 victory. They never left Walker out of the lineup again. He earned All-Ohio Conference honors and was named UA's Most Valuable Player in 1948-49 as Akron captured the Ohio Conference Championship. And despite being outscored by his teammate Hank Vaughn for three seasons, he got some measure of revenge as he ended up with 1055 career points, 14 better than Hank. That total, in 1950, ranked Walker second in the all-time scoring list behind another Hall of Famer, Fritz Nagy.
