Yes ROLOMOKO was probably the first defensive line with a nickname that I can remember. The Giants traded an aging Roosevelt Grier to the Rams for strongman John LoVotere prior to the 1963 season. Rosie of course went on to star with the Rams Fearsome Foursome of Lundy, Jones, Grier, and FTD Man. LoVotere had a couple of good seasons and then hurt his knee as I remember and ended his Giants career in 1965.
RObustelli, LOvotere, MOdzelewski, and KAtcavage were the guys. And I didn't make it up. ROLOMOKO was their nickname.
But then, maybe, perhaps it's the alzheimers kicking in?!
