They are in a bind and have to trade Harper, Rizzo won't want to get a 4th round supplemental pick for him. Trade Harper and go with an OF of Eaton/Taylor/Soto, with Robles likely up soon as well.
Honestly, if they trade only Harper, they're winning the division. Book it.
If we could get a haul for Harper, I wish we could do it without it meaning we are in "sell" mode. Harper is torturing our lineup and my guess is he isn't going to suddenly regain his MVP form. He seems to strike out twice every game, some games three times. We'd be better of without him.
The Nats aren't going to get a haul, but that trading Harper doesn't magically make you sell mode. The guy is hitting .205/.324 /.457 since May 1. He is completely replaceable.
And honestly, if he returns to his MVP form, it's already been shown that it's not enough to get you to the playoffs. Everyone else hitting and pitching well with Taylor playing CF > All that and Harper hitting well.
So you're faced with choosing between a 4th round supplemental pick, or whatever prospect a team offers.
