The Lerners are paying him. They will want to get something out of it.
They can do what there were noises they wanted to do with Strasburg and make him a coach or something to fulfill his contract. Maybe Gallo can be a weight trainer. Maybe they can take the player as invested commodity idea to its fullest extent, and have them help do prep work on gallery place for Leonsis.
Along those lines, maybe they can give guided tours at the park, take turns being some of the racing presidents, and so forth. If they really wanted to get people down to the ballpark and get their moneys worth, maybe they can actually be living hands of the former giant curly W clock. There are so many possibilities to get something out of it while not having to worry about working them into the lineup.
