Kingsman, rather than trying to mine a dry hole, let me try an alternate idea.
How were his grades and scores? While you noted that a track scholarship would not cover enough financially, there is a certain level of college which give more in financial aid per recipient in the form of grants than other powerhouses give to athletes. Since he's the top pole vaulter in Mississippi, even though not top ten nationally, if he has the grades and scores, track may be the way to approach those schools.
Now, since he has already graduated, matriculating in 2019 isn't possible; but 2020 could be possible.
This could allow you to leverage a budding asset (PV) rather than leveraging no asset.
