Pat at WHYGAVS nicely details the history of Pirates' logos and uniforms. In the comments over there, Azibuck points out the roid-enraged appearance the players take on by 1997. This occurs abruptly in 1995, as the players simultaneously sprout evil menacing faces, just in time for the black-hearted Nuttings' sinking of the team in 1996. Curiously, the home player also suddenly holds out one of his hands. Just behind him, the road player angrily grips his bat. Together they're clearly demanding money for the Nuttings, as in "Give me your freakin' wallet, sucker."
