Your clubhouse leader for least surprising press release of the 2012 offseason:
Apart from being 100% expected, this is fine. Any manager who isn't purely a placeholder deserves at least one full season. In 2012 Davey will have his players executing his strategies. We'll see what happens.
UPDATE: WaPo's Adam Kilgore says that current bench coach Pat Corrales is stepping down, to be replaced "by a younger coach who could potentially replace Davey Johnson as the Nationals' long-term manager after the 2012 or 2013 season."
That too just makes sense, as Davey will be the oldest manager in baseball in 2012, and if the Nats have a successor in mind, it's probably good to lock him in, and get him an apprenticeship of sorts under D.J.. If the Nats are serious about contending in 2012 and beyond, they'll want a manager who is familiar with the players, rather than someone who is coming in cold from outside the organization.
