It was a joke tafnut- in the early 1960's, the LSU Tigers were one of the few major college football teams that even had a regular weight training regimen- almost no premier baseballers lifted. Ted Williams was big on pushups, wrist rolls, and "cals". Basketball players were told weights would ruin their shooting form. Wrestlers, track's weight throwers, football linemen, and rehabbing footballers w/ knee injuries were the first to regulary strength train (i.e. Tucker Fredrickson, Namath and Sayers, 1965 NFL draftees who did leg lifts in therapy). Jim Bouton broke the silence on MLB'ers use of "greenies".
When LSU started getting results on the field, and some articles were produced about their regimen, college and h.s coaches took notice (and supplements entered the picture, some clean, some less natural).
