Great school and baseball program. The academic money sounds good.
Knowing that your son is of some interest by Carthage, and the money sounds good, is your son looking at other schools in the area? DIII, DII, DI? Do you think your son can make the team at Carthage, or is he a DII or DI hopeful? Does he want to play right away, or maybe sit for a year or two, especially at a DI school?
These are tough questions that have to be "honestly" answered. All kids want to play DI, but the key is "playing!!" I know you didn't mention anything about DI, and if his focus is on Carthage, by all means pursue the opportunity. Their baseball program speaks for itself. If he is interested in a DIII school, Wisconsin and Illinois have some very good academic/baseball schools to choose from.
Also, look at what position players are graduating for your sons particular field position. Look at their stats to see how your son matches up to those players. Regarding transfering, go to the NCAA website and look-up the information about "Transfers." The rules changed this season so you need to do further research in that area. What position does your son play? My son is at a DIII school in New York. Always looking for good players and the academics are great at his university.
Best of luck to your son and to your family in the search. Once he decides and then goes to that school, and then plays baseball there, what a great feeling you have as a parent.
