is probably the world's biggest football player.
The 7-foot, 440-pounder is a senior at King (Riverside)
, in the Inland Empire area of Southern California. According to his head coach, Kevin Corridan, Krahn goes by the nickname "Junior."
Krahn was 6 feet tall in sixth grade, and was 6-foot-5 when he entered high school. As a 6-8, 330-pound sophomore, he cracked the varsity roster but recorded no statistics.
Since then Krahn has grown another four inches. MaxPreps believes he is the tallest player on a high school football roster this season.
He is taller than any player to ever play in the NFL, and is roughly the same size as WWE superstar Big Show
There's no doubt that, right now, Krahn is a raw player. He excels in the weight room, but struggles with his footwork. He is relatively new to the sport, but is working hard to improve.See more photos of 7-foot, 440-pound John Krahn
"I've had minimal experience," Krahn said. "I started in high school, but I've trained my way through, going to different camps."
Krahn told MaxPreps that he's attempting to shed some pounds by adhering to a 3,000-calorie diet comprised mainly of fish and chicken.
"I have to lose weight, for our team," he said.
Losing weight could also be beneficial for Krahn's personal football future.
He participated in USA Football's National Development Games in Los Angeles over the summer, where he definitely caught the eye of several college coaches in attendance.
"We had Division I coaches on site that said they'd consider offering him if he lost some weight," USA Football's Jimmy Thomas told MaxPreps. "They think he could be a force at a lighter weight."
Not only did Krahn see work in the trenches at the National Development Games, but he was also used in the backfield in jumbo offensive sets.
Presently, Corridan believes Krahn could be a good candidate for junior college, as a possible launching pad into a football career at a Division I school.
If Krahn's football career doesn't pan out, he could be even more intimidating in his other preferred line of work.
"I want to be a police officer later in my life," said Krahn.
