Lots of great advice and suggestions mentioned thus far. It appears his current offer has satisfied many of his checklist's priorities. If a concern is whether by playing at a Mid D1 may hinder his exposure or draft status years from now, I can provide a few points if interested.
PM me if this applies.
Best of luck, very exciting times. May get a little chaotic but few will have the opportunity to experience it. Enjoy and soak it all in!
