To say that Martin Luther King (Riverside, California) High School senior John Krahn has NFL size would be an understatement.
Nobody in the NFL is as big as he is.
Krahn stands 7 feet tall and weighs in at 440 pounds.
To put it simply, he is much bigger than the high school linemen he goes up against. In fact, he may be the biggest football player ever. According to Stephen Spiewak of MaxPreps, Krahn is believed to be the tallest high school player in the country and is taller than any player in NFL history.
According to Spiewak, Krahn has always been big for his age. He was 6'0" in sixth grade, 6'5" as a freshman and 6'8" (and 330 pounds) as a sophomore. And he's just continued to grow.
As the highlight reel of Krahn shows, opposing lines have to team up to block him.
Just watch the video and see how fellow high schoolers fare against Krahn.
