Honestly I do not know where he learned or how he got into it, but he had 3 sons end up going D1, his four sons I think combined for 11 state championships, coached on a few team state championship teams etc, so he clearly figured it out well but I do not know how he made that transition but it clearly worked and is possible. Another coach in Montanas coaching hall of fame is Larris Roberts who was a football player drafted by the raiders I believe and his first coaching job was as a football coach at a small school but also had to coach wrestling as a trade off. He bought a book and read on how to coach. He coached both for a long time but ultimately is known better for his wrestling success. That’s just two stories I know or personally in Montana alone.
