Meet John Krahn, 7-foot, 400-pound high school lineman

LOS ANGELES (AP) John Krahn is among the biggest football players ever to don pads and a helmet. And he's still in high school.

The offensive lineman who recently started his senior season at 7 feet tall and 440 pounds was even at one point deemed too big to play the game that usually worships size.

Krahn says he was too big for his youth football league in Southern California.

But now he lines up with - and towers over - the Martin Luther King High School Wolves in Riverside.

His combined height and weight make him bigger than any current NFL player and possibly bigger than any NFL player ever. Seven-footer Richard Sligh played for the Oakland Raiders in 1967, but NFL records put his weight at a mere 300 pounds.
