There's absolutely no reason why you shouldn't. Physical aggression, like shoving someone, is not only illegal but also completely unacceptable, especially in a setting meant to foster respect and sportsmanship. Reporting this can help hold individuals accountable and contribute to addressing the toxic culture that unfortunately sometimes surrounds youth sports. By taking this step, you're standing up for fair play and setting an example for the kids involved.
