XFL founder Vince McMahon has said that the league will not accept any players with a history of criminal behavior or character issues.
You want someone who does not have any criminality associated whatsoever with them. In the XFL, even if you have a DUI, you will not play in the XFL, McMahon said in a press conference in January 2018. So that will probably eliminate some of them, not all of them. If Tim Tebow wants to play, he can very well play.
