It would have to be to a team that sees MP as a starter. Otherwise why trade a young guy for an old, moderately expensive backup? But what other teams would Parkhurst be a starter for? Not many.
Maybe chivas usa. Oh wait... Anywho, i cant see anyone wanting him that bad. Maybe a team like rsl or orlandothatwould want a veteran backup, or houston or Chicago (both teams bottom oftheir conferences). Honestly though, he's on 300k a year, no one is gonna pay him that when his contract is up.
