Interesting question with some great responses. My son just signed with a great JUCO program. I wondered the same thing. If he has a monster senior season mashing the ball, and a DI happened to need a power hitting first baseman. What would we do?
I have to say it would have a lot to do with the school, the offer and the conversation he has with his JUCO coach.
He's not at the JUCO for academics, he's a great student with good enough grades and test scores for just about any DI short of Ivy league type schools.
He's at a JUCO for baseball. To get to a DI school at some point in the future...or not. If that point comes after his senior season in HS, then I guess he's got some soul searching to do!!
