I'm not for sure that it is follow the money/mound. In our case, it was suggested to 2015 son that he become a PO this past Summer. He was leading his team in hitting at the time. The main issue was injuries as it was related to me. Did not want him getting hit by a pitch, didn't want him twisting an ankle, didn't want someone sliding back into to him at 1B, etc. etc. These suggestions were from people that we trust. It was hard at first but son got to where it kind of liked being a PO.
Now he may hit some for his HS team....just don't know yet.
