The Cleveland Browns are the only team in the NFL named after a person, but there's some confusion as to who that person is.
Call the Cleveland Plain Dealer sports department and you'll be told Paul Brown. The Official NFL Encyclopedia of Pro Football also credits the legendary first coach and general manager of the team. But according to the media relations office of the Browns, the team is named after the "Brown Bomber," boxer Joe Louis.
About the only thing that seems certain is that there was a contest to name Arthur McBride's professional football team in 1946. Fans were asked to submit their suggestions along with an essay, with a $1,000 war bond going to the winner. Navy Sailor John J. Hartnett won the contest with the name Panthers, but it was never used.
