How about John Pingel, AA at MSU in 1938, averaging 5.5 ypc as a half back in his All American season, and also punted 99 times for 41.8 yards, totalling 4,138 punting yards, an NCAA record which still stands. Not sure if that's a good or bad thing.
Nothing sums up 1930s college football like an All American half back who still holds a punting record 80 years later.
