There are no easy answers to the JUCO equation, and my 2017 gave it some thought before deciding to choose the 4-year school that best fits his academic goals over having to do this all again in two years. Frankly, he is worn out from all of the campus visits, coach talks and texts, and sorting through the merit aid and financial aid considerations. And I like the fact that he has gone back to the same question over and over again: if the baseball was not there, would you be happy at the school? He would definitely not be happy at a JC sitting on a bench or not playing at all and then figuring out where he will finish college. Whereas he would be satisfied (maybe not happy) at the four year if the baseball does not work. He will get a great degree in his intended field and then hopefully move into the workforce. He has no aspirations of pro ball, and he is academically strong, so he has always had the right perspective that the baseball is the lower priority.
Good luck to you and your son on the decision. No matter what level he chooses to play at, it is a real privilege to even have the chance to be playing baseball post-high school.
