Ian Kennedy: head hunter
Alex Rodriguez: unpunished doper
Ryan Dempster: vigilante
Jhonny Peralta: punished doper who cashed in big
Brian McCann: asshole enforcer of unwritten baseball protocol
Carlos Gomez: violator of unwritten baseball protocol
Paul Maholm: Gomez tormentor and instigator
I'm sure there are other worthy candidates but these are a few who easily come to mind.
