If he can get into Lehigh, he should have a free ACADEMIC ride at USF. Florida and other states have programs that let kids attend state schools free, or depending on GPA/SAT combo, a massive discount. And Florida has perhaps lowest in-state tuition anywhere.
Maybe that’s the gig: Preferred walk on at USF, or be a star at LU and pay $20k or whatever waiting for financial aid to let him know? I know of a kid who took a similar cheaper route at an SEC school last year (where he’ll never play) vs. a PL school (where he would have).
Money talks, but no way is a degree at USF comparable to one at Lehigh — unless you’re going to be an artsie.
