Last time I checked, that elite baserunning is a factor included in measuring the fact that he's the 16th best offensive player in the NL (not even baseball).
The Braves finished 13th defensively, even with Maybin in CF, CJ, KJ, Olivera, and Garcia at 3B, and a mix-and-match group in LF.
How about trying to fix the offense first? Shelby Miller lost 16 straight games with an ERA that was below 3.10.
How is adding Heawrd not fixing the offense? You realize only Freeman would of been better this year, right?
