Kinda reminds me of Last Chance U on Netflix, but with a different angle. While Last Chance U seems to be about a coaching staff that has set out to win at all costs (not a bad thing), Undefeated shows coaches who are trying to build men of character through football. The coach says as much at the beginning. I love the refrain throughout: "It's not how you handle victory, but defeat that defines you." A great life lesson and an inspirational film.
