Robinette was a prolific scorer at a tiny, rural HS in southwest Virginia. Apparently year at prep school didn't help him that much to prepare for mid major college basketball. Played against weak opposition in HS. Based on size, potential, etc., can't blame Danny for recruiting him and hoping to "coach him up".
Don't know his family circumstances. Hopefully, he continues his college education, perhaps at a local school near home, like UVA-Wise. A D-2 school, he probably could play ball there if he wants. Wish him good luck with his future. If he left MU already, he's lost about half a semester of school work, unfortunately.
