this is the original screen used Bobby Boucher (Adam Sandler) No9 jersey from the USC Mud Dogs. I believe this is 1 of 3 that were orignally made for adam sandler in the movie. One was sold at auction after the movie was released as part of a complete set including , helmet , trousers and boots. I purchaced this one and the other No9 jersey from sports robe a few years ago. One i have framed and displayed and the other is in a box in my wardrobe. I also own no51 which is worn by jonathan loughran. The Coa states they were screen worn and that there was 3 number no9 jerseys used in the production of the movie and i have no, 2 and 3. They were all purchaced from sports robe who made the original costumes for the movie
