The XFL is all the rage. This professional football league is the brainchild of none other than the WWEs very own Vince McMahon. Never one to shy away from a challenge, the WWE CEO took matters into his own hands, and shouldered the burden on his broad shoulders. At inception, McMahon pledged to invest a whopping sum of $500 million in the XFL over the course of the first 3 years of the league. The XFL garnered substantial credibility with the appointment of a football commissioner in the form of Oliver Luck, and this time around the XFL seems to have staying power.
