You are about where my son was at that age, though he was probably 77-78 at that time...same size and weight. He was 5-10, 160 and throwing 87-88 the summer after his junior year when he got offered and accepted at a mid-major D1. I see no reason why you can't get to those numbers. He just worked on his strength and velo and also his hitting. If you truly want a better academic school, then base your decision on that. Play on the best travel team you can find, you'll see better competition there than in HS in most cases.
