Clearly we aren't going to agree on his defensive measures; how about the bat? There does seem to be significant decline in the post-steroid testing era. This team needs offensive production from its outfield and in a really bad way.
His .334 wOBA in 45 games with the Marlins in 2011 would have placed him second in wOBA for Nationals OF'ers. Only Mike Morse was better.
Even better wOBA than Werth.
