Continuity mistake: During the Warriors VS Ducks game, Charlie is driving down the rink and it cuts to a wide shot. You can see the puck is dropped and intercepted by a Warrior. In the next shot, Charlie takes a shot which the Warriors' goalie blocks. Charlie couldn't have gotten the puck back that fast, no matter how good he is.
Continuity mistake: When Portman tackles one of the varsity team's player through the glass, his helmet's attachment changes, in the face off, it's different than after the tackle.
