 Unlike the NFL, but like the World Football League and Arena football before it, the XFL allowed one offensive player to move toward the line of scrimmage once he was outside the tackles.The heavily hyped "no fair catch" rule (announcers tended to mention it on almost every punt/kickoff) was paired with a five-yard zone excluding players of the kicking team around potential returners before the ball touched them or the ground, similar to rules in Canadian football, rugby football, and contemporary NCAA rules (where the term "halo" was applied, though the XFL called it instead the "danger zone").But instead of making punt returns more exciting, it often had the opposite effect, since the XFL players' inexperience with the rule caused a high number of game-delaying penalties.
