Watch High School Punter Catch His Own Punt And Return It For Touchdown

What??

Nope, if it's behind the line of scrimmage, he can advance the ball.

The only way it would be dead, is if nobody touched it after it was kicked, then it's just a normal punt.

An offensive team member CAN advance a blocked punt as long as it is behind the line of scrimmage. in the video, the punter clearly caught the blocked punt behind the original LOS, so it is a legal return.

Derp

It’s legal because the ball was still behind the line of scrimmage
