That's deffinately Freddie Adu, you don't see Freddie Adu because he's not on the USMNT, and it's not a USMNT commercial, it's a NIKE commerical. I don't think it was ever supposed to be Jim Rome. It's just mocking the general view of soccer from your average American.
1) That's adu who does the move in the empty stadium 2) Yes it's Johnson in the group of players, not Adu. Adu has never been called up to the senior national team. 3) No, it's not really Jim Rome.
