Son's college team has drafted players come back in the fall semesters to work on completing their degrees while still playing pro ball. They are good roll models.
I met a young man who opted to not go to college (and not going to the CWS one year) and instead take "life changing money". Recently retired from baseball with a new wife and baby, his choices for college were Harvard, Penn, or William & Mary. He had a pretty good "hook" to get in lol, but he must have been (and still) incredibly smart.
