He was telling his players in the middle of a game. He was more worried about his kids than what was going on during the game. It means he cares about the kids.
True story Scott was scrimmaging a team(Batavia) at SK this year. Carr told half the kids during the game they better have a hair cut by Monday or they wasn't playing. Sounds like Carr was more of a father figure than what these kids have at home.
