Every since our first game versus them in '95, they have been the Panthers/my mortal football enemies. The Saints and, to even a lesser extent, the Bucs rivalries pale in comparison. I hate the Cowboys, but playing one another, I'd pull Jerry Jones' squad.
Heck, I really hated the Tom Brady Bill Belichick Patriot teams, but I favored them in the SB against the Falcons. Oh yes, their implosion was chef's kiss glorious in that game.
