Lerners should sell, but keep Rizzo and Davey. The pair did well when Ted Lerner spent, and have rebuilt on a shoe-string. Think of Rizzo's deals, and the spectacular Soto for Wood, and CJ, and Gore, and the rest. And Davey's managing in 2019.
Ownership of a baseball team in DC SHOULD be worth a lot. Maybe not as much as the Mets or Dodgers, but sports ownership is a prestige buy. Remember Jack Kent Cook, who owned the Redskins for the pleasure of inviting famous people to his box, and then the greater pleasure of holding the Lombardi Trophy.
