There is a huge difference between recruiting for college football and soccer. Kids may be overlooked, even frequently, in soccer but the large amount of camp opportunities, college recruiting staffs and dedicated coordinators, available film, recruiting services, etc in football reduces the number of overlooked football players to a minimum. Head coaches, staffs, even recruiting services have analyzed the guy with whom you have an obsession and not seen a P5 level recruit. If he wants to walk on and try to earn a scholarship at Purdue, good luck to him. I'd support him just as I would any good student-athlete. It worked for Horvath after all.
