I noticed recently that NFL team names can be grouped into one of five categories: 
  1. Birds:  Cardinals, Eagles, Falcons, Ravens, Seahawks
  2. Cats:  Bengals, Jaguars, Lions, Panthers
  3. Large Mammals:  Bears, Broncos, Colts, Dolphins, Rams
  4. People Group, Historical Figure, or Occupation:  49ers, Bills, Buccaneers, Chargers, Chiefs, Cowboys, Packers, Patriots, Raiders, Redskins, Saints, Steelers, Titans, Vikings
  5. Other:  Browns, Giants, Jets, Texans
Yes, I realize it's a stretch to call a dolphin a large mammal, but it's technically accurate.  And a Charger is someone who charges into battle.  Stupidest team name:  Browns, named after one-time owner Paul Brown.  That's the best they could come up with? #sports
