Bobby Boucher (Adam Sandler), a socially inept 31-year-old from the swamps of Louisiana, is home schooled and sheltered by his over-protective Mama (Kathy Bates). His only contact with society is his waterboy job for a college team where the players relentlessly make fun of him, and his coach doesn't let him fight back.

This all changes when Bobby gets a new coach (Henry Winkler) who lets him stand up for himself. Bobby finally unleashes years of pent up rage and is transformed into the most devastating tackler on the team. Now Bobby has to learn how to play football and go to college, all behind his Mama's back. Let's just hope Mama doesn't find out!
