There aren't many ex-Nats I cheer for, but I definitely am still pulling for Max. I can't say I like the Dodgers, but I don't like the Giants either, or the Padres for that matter, or anyone else they are likely playing against!
He didn't choose to leave. He seemed relatively open to going somewhere to allow the team to get a good return. He said he refused to go to the Mets, which gets him extra credit in my books.
I'm all about him continuing to do great things and solidify his place in the very top echelon of pitchers. He won a World Series and 2 Cy Youngs here, so he's not in danger of overshadowing his accomplishments as a Nat.
