I automatically think of tumbling when I think of Rookies and vice versa. All trouble boys learning a sport together. They learn to build a friendship with their members and learn to love the sport.
both have delinquents and they a passionate teacher supporting and believing in them. Same concept, one is about baseball and the other about life. You'll love Rookies.
Both titles deal with a similar issue: an inspirational teacher who makes his students believe again in themselves and their dreams.
