From Dave Nichols:
This move makes the Nationals a worse team.
Absolutely wrong. This is one of the more extreme cases of addition by subtraction. Nyjer Morgan was such a huge negative just replacing him with someone who knows how to be a professional, makes the team better. The better alternative would have been to get rid of Morgan in November and aggressively look for a centerfielder when they had the full offseason to do it.
I don't get what Rizzo's thinking was this offseason about Morgan, to be honest. He couldn't have expected Nyjer Morgan to get appreciably better. His baseball IQ is almost negligible and that's not ever going to get better. It's so bad that it completely negates his one asset, speed. And this completely ignores his other deficiencies, which are numerous.
Getting rid of Nyjer Morgan back in November was an easy decision and if he (Rizzo) can't make the easy decisions, I can't trust his judgment in making the difficult ones.
