I always heard certain names/nicknames in sports or reading sports stories, and thought 'That's a cool name'.
Jari Kurri, Maurice 'Rocket' Richard - NHL
Urban Shocker - MLB
Satchel Pagie - Negro Leagues
Boomer Esiason - NFL (a stretch, but)
Cassius Clay/Mohammed Ali, Joe Frazier, Rocky Marciano - boxing
Any interesting names ever pop up when you think of sports?
