In March 2018, Villapiano joined with former NFL stars Harry Carson and Nick Buoniconti to support a parent initiative called Flag Football Under 14, which recommends no tackle football below that age out of a concern for the brain health of the young players. He said, "At some point, those of us who have had success in this game must speak up to protect both football players and the future of the game, and supporting 'Flag Football Under 14' is our best way to do that."
