Great question. I have three boys playing youth lacrosse and I don't know of a single dad who has placed his kid on defense, not saying it hasn't happened.

For my kids football team every single kid that is playing quarterback has a dad that is either assistant coach or head coach. The rest of the backfield is the other dad's kids
