Defictionalization: The NHL franchise. Though when they ditched the uniforms from D2 and the "Mighty" part, they became a respectable franchise and even won the Stanley Cup.
Amusingly, given the theme of the movies, the cup-winning Ducks team was known for being relentlessly physical. They led the league in fighting majors that season.
Deleted Scenes: At least two in the first sequel. The first took place after Team USA follows Bombay on the golf cart roller blading. Portman and Fulton begin to bond, Coach Bombay and Ms. Mc Kay get to know each other, and the scene ends with Fulton, Guy, and Jesse crashing the golf cart. The second involved the team members who didn't go to Rodeo Drive getting into a brawl with the Iceland team while hanging out at the beach.
