alligator arms
n.pl.— «Sanders is a converted running back, as was Monk, who didn’t take to wide receiver at first. “He had alligator arms, know what I mean?” said his former coach.… “He didn’t reach for the ball at first. If he hadn’t had the USFL experience, he wouldn’t have made it in the NFL because no one would’ve given him time to develop.”» —“Monk, Clark, Sanders Dealt Pro Bowl Snub” by Tom Friend Washington Post Dec. 21, 1989.
