I haven’t watched the XFL and don’t intend to, but this popped up on Twitter after the first week of play and I have to grudgingly concede they may be on to something with it.
As the announcer noted, if the kickoff doesn’t go past the 20-yard line, the receiving team gets the ball on the 45. Touchbacks go to the 35.
This appears to eliminate grown men running full bore at each other, while not turning kickoffs into a touchback-fest. There’s safety and opportunity. Pretty clever.
