Eliot Johnson is not a particularly good baseball player. I think his record speaks for itself. He's a AAAA utility guy.
The upside on Uggla is better and I think he should have been on the roster instead of Constanza or Reed Johnson, but let's not get carried away with this idea that Uggla has been terribly wronged. He had a great June and a decent July (due solely to impressive power numbers), but he really slid off the table (and slid is the polite term). He's got no one to blame but himself for the situation he (and by extension the Braves who are paying him $13 million for his underperformance) is in. I'm no strict adherent to "little ball" strategy, but the playoffs are different than the regular season and Gonzalez and company rolled the dice. When you realize that Fredi and Frank figuratively want to spoon with Uggla, you can only imagine how difficult the decision was for them.
It's too bad Pastornicky (and Pena before him) got hurt, but some of us thought a deal for Boniafacio would have made sense at the deadline regardless of Pastornicky's presence and health at the time. But that's water under the bridge. Wren waited too long to have a decent option to Uggla in tow after Pena's injury and with Pastornicky's injury, the replacement became Janish or Johnson. zito would argue LaStella should have been in the conversation. I frankly don't know.
So there's plenty of blame to go around (Uggla and Wren in particular) and the Braves are left in a situation where it's difficult to let a guy play himself out of a slump seeing it's the post-season. Maybe we'd have been better off not being in the fight for homefield advantage and Uggla could have been given a full week to try and swing himself back into a groove. Lots of questions.
