I recently had the opportunity to play with two persons both under 16. Yes both of their fathers had been on the field with them.
At no time did I feel unsafe or nervous with them on the field.
Both of them showed and excellent effort to keep up to the old farts. I was surprized and amazed how well the handled themselves. They obviously had been taught, and understood normal safe handling.
I would definitely take the field with the "Wonder Twins" again.
