Most good teams have old players. The Tigers, Mariners, Dodgers come to mind. Most teams aren't the Cubs or Red Sox. This notion that we are quickly becoming the Phillies is nauseating, and the oldest team in baseball tag will be removed next year.
An injection of youth would be nice this year, but isn't entirely necessary. A year from now there's a very real chance that guys like Alford, Tellez, SRF and Greene are close to contributing.
