This back and forth is going to go on for a while. If the Phillies haven't actually made an offer, it's because they want Machado. It's obvious Machado doesn't want to go to Philly. Harper likely wants LA, and is holding out for their best offer. My guess is Harper leverages Philly to get a better deal in LA, or just comes back to the Nats, although I think that ship honestly has sailed.
