Interesting piece on Koehler in Sports Illustrated (Jan. '09):
Reeve Koehler received his first football scholarship offer before he ever strapped on a pair of shoulder pads.
Koehler, a 6-foot-4, 280-pound eighth-grader from Kaneohe, Hawaii, was always too heavy to play Pop Warner football. But Koehler, the 13-year-old brother of Arizona freshman offensive lineman Solomon Koehler, impressed Hawaii coach Greg McMackin so much during drills at the school's camp this past summer that McMackin extended a scholarship offer.
Eighth-grader receives offer from Hawaii before ever putting on pads
As a freshman, Koehler could bench 225 lbs 12 times & 155 28 times. He had a 29" vertical even then, showing surprisingly explosive power for such a young guy. More recently, he put up 23 reps of 225 at a combine in May.
