If I’m reading this right, your son plays baseball now but doesn’t want to play in college, but wants the college to have baseball so he can watch? If so, be careful of northern schools that have baseball but may play a lot of it in the south over spring break, over long weekends in tournaments, etc. My daughter went to school in Florida and there were always northern schools coming down to play, but rarely did schools head north much farther than the Carolinas.
CU doesn’t have a baseball team (used to) but some of the D2 schools around here do. It is a little easier for them because the travel isn’t so bad and they can reschedule more easily than the D1 schools with plane travel.
