i tried to uncover some defense mechanisms in the movie She's the Man, starring Amanda Bynes. here are some clips that i came up with and the defense mechanism i believe to be present.

this clip shows that Viola's ex boyfriends didnt accept that he once cried during a soccer game and tried to make up an excuse for why he had tears in his eyes. this stage would be rationalization.

this is the movie trailer. it shows how Viola wants to act out against her team being cut by dressing up as her brother and trying out for the boys soccer team to show that she is good enough. this could be considere projection.

i also believe that her aggression for soccer is an example of displacement, because she is using her passion and redirecting her rebellion into a safer outlet.

Hope this helped to clear those up!
