Davey's managed to not overwork the bullpen even when some say he is lifting starters too early. Last year, Storen and Clippard both were in the top 25 in appearances. This year, the Nats do not have a reliever who has appeared in more than 9 games. About 30 relievers have already appeared in 10 or more games. Clippard has only appeared in 8. There are about 60 relievers who have made more appearances.
