Totally agree. I think baseball son likely needed baseball to motivate him to attend college at all, let alone come away with a masters degree and, more importantly, now possess the work ethic to succeed in other life stuff. Not D3 but some of the same principals apply.
And from players I have coached, I have had plenty of feedback that verifies this "beyond baseball" well-rounded bond and networking is particularly strong in HA D3 and similarly classified schools.
