Cuba's Javier Sotomayor is the world record holder in the high jump. He's the only athlete to ever clear 8 feet, setting the record at 8 feet and 1/4 inch. Sotomayor was basically designed to be an incredible jumper, standing a long and rangy 6'5 with startling athleticism and explosive speed, especially for a man of his size.
Texas Tech wide receiver Jakeem Grant is not Javier Sotomayor. They play very different sports, and the Red Raiders star is not a statuesque 6'5. His official university bio lists him as 5'7, and that might be a little charitable. But he does have one thing in common with the Cuban legend: He can jump like crazy.
