Gabriel Rosado and Jesus Soto Karass are gatekeepers. If you know a boxer by name he probably isn't a journeyman (same with bum, tomato can, taxi driver) I'm not sure of the exact definitions though.
Buck Smith. Over 180 fights. He won almost all of them, but lost every time he stepped up against anyone half way decent. He fought quite a few big names including Chavez and McGirt.
