After high school, he attended Purdue University, where he played basketball under head coach Ward Lambert.

In sixteen seasons at the high school level, Eddy's teams won 13 Sectionals, 6 Regionals, 3 Semi-States & 1 State Championship.

During his 15 years at Purdue, he was able to attract a number of talented players, including All-Americans Terry Dischinger and Dave Schellhase.

While finishing as Big Ten runner-up on three occasions, Purdue failed to win the title during Eddy's tenure, and never advanced to postseason play.

He retired from coaching after the 1964–65 NCAA Division I basketball season and accepted a position as an associate athletic director at Purdue.
