Larry was a very good running back. He may have been the best short yardage back in the history of the NFL. He was extremely powerful! That is where he was most effective, during the Dolphins glory days Mercury Morris and Jim Kickk helped carry the load on the ground.

Back when I was a kid this was one of those words/phrases meaning "to have sex with".

Look up ugly runner and this bugger jumps right off the page at you. Tough, nasty, and willing to run over his grandmother, twice if necessary, to gain a yard.

Tough as nails.  An old school powerback,  that would bust straight up the middle plowing through defensive lineman often carrying 2 or 3 of them with him!
