Bandits are likely 2nd at ~50.
Bills or Astros would be probably be 3rd at about 40.
Though it's very possible and actually likely that I've seen the Habs, Bruins, Leafs, &/or Flyers more than them.
Fish would be the most common non-Buffalo based & non-hockey based team as they were almost always the Bills opponent if I only got to 1 game a year.
