I'm not exactly sure how anyone can be shocked with how some of these guys have underperformed. Certainly the extent to which they have sucked is alarming, but we ALL knew it was possible.
We all knew Heyward was prone to being injured and inconsistent.
We all knew JUpton was strikeout prone and had questions about his motivation. He wouldn't have been available otherwise.
We all knew Uggla was turning into a low average, high power guy with a good/great walk rate.
We all knew BUpton also K'd a lot and likely would hit for a low average.
We all should have known Simmons wasn't a legitimate leadoff hitter.
So we are seeing everyone but CJ, Mac and Freeman play towards their worst case scenario. It sucks, but none of it came out of the blue, and I doubt much of it is Walker's fault. The Braves pretty much have only one choice: hope the studs start playing like studs.
