However, I'm skeptical the Nats will have enough firepower to compete...I'm sure at some point Rizzo will need to get the OK from the Lerners to make a move and they're so stingy I'll be pleasantly surprised if they sign off on it.
I wouldn't say stingy (see Werth signing, two #1 draft picks signed, Gio, Zimmerman, etc), I would say they are practical and know what they have, and don't need to sacrifice the long-term for the short-term success they are seeing now.
But I too am skeptical they have enough firepower to compete. Still early, but if the offense gets a little bit better and the pitching gets a little bit worse (can't get much better at this point), they are still in a good position.
