It's tougher to get into a lot of D3's than it is to get into D1's....especially some state schools. That being said, regardless of if it's D1, D2 or D3 if a HS kid is already having grade issues, the jump to college is going to be tough enough.....then throw in the time committment for baseball and he's looking at serious problems right from the start. JUCO to work on grades/time management, etc may be the best option then look to go to a bigger school after a year or two if he shows he can handle the academic side
