The XFL, or the Xtreme Football League, is a professional American football league that was originally founded in 2001 by Vince McMahon, the chairman of WWE, and NBC Sports. The league aimed to offer an alternative to the National Football League (NFL) during the NFL’s off-season and featured various rule changes, including a “scramble” for the ball at the start of each game instead of a traditional coin toss and a rule that required all players to stand during the national anthem.
