Before 1972 , freshmen were not alloeed by NCAA to compete on varsity teams. The records I found say "On freshman team , no varsity action" Seems I remember reading about J.V. games but there are no records , and few defensive statistics for even varsity games. Question for old timers. Would their sophmore year be considered like redshirt freshmen today? Did they practice with the varsity or separate? Seems there was exceptions in 1950 and 51 or 51 52 for Korean War?
