It's a good thing that everyone here appears to think very highly of Brohm (including me, but I don't know that much about him), both as a coach and a person.
If I had a kid who was a 3 star at football and had high academics, Purdue would be a great choice for him I think if he were into engineering.
NW would be another very good choice as well on both counts, but playing football AND excelling at academics is tough, especially when the academics is not part of the usual jock stream of courses.
