In adding Dan Haren, the Nationals have mastered the art of stacking the rotation. Strasburg-Gonzalez-Zimmerman-Jackson was decent enough, but now that Haren is in there, the pitching it stronger. Haren is an incredible consistent pitcher, and while he may have lost some flair since his days with Oakland and Arizona, he's still a great pitcher.
Come to think of it, this is a great week for Washington. Haren is signed, RG3 has a monster game, the Wizards stayed out of last, and Ovechkin couldn't blow a game cause there's no Hockey. So...DC residents should be thrilled.
