Off the top of my head - Terrell Owens, Pete Rose, Jose Canseco, Bill Romanowski, Johnny Tapia, John Rocker, and Marty McSorley (or any hockey player who bashes opponents on the head from behind.)

Guys I don't necessarily hate but love to cheer against: Brian Billick, Mike Shanahan, Jerry Jones, Al Davis, Jason Varitek, Kerry Collins, Kurt Warner, Kobe Bryant, Reggie Miller, Keyshawn Johnson, and Chad Johnson.
