Ray-John, Rah-John or Rye-John?

Celtics PG Rajon Rondo has the most commonly mispronounced named in the league. Network announcers usually say it 'Ray-John' but Celtics fans maintain it should be 'Rah-John.' To further complicate matters, this official NBA page suggests 'Rye-John.' RYE-JOHN?!?

And can someone give me a straight answer on Andray Blatche while we're at it?
