There are a lot of kids that do not play football that have the need to finance the entire 4 years of about $250k or so. Maybe they get some help or maybe some sort of academic scholarship, but financing the full boat is all to common for a higher education. If he has to finace only half that for a really good BC degree and his family is devote Catholic and BC is in very high regard, it makes sense unless another P5 school or very high academic College gives him a better opportunity.
I haven't heard of him getting a committable full ride somewhere that would make you shake your head at him walking on there...
Curious, what is the cost at Rutgers for a PWO as compared?
