I truly believe the Braves FO thinks Kemp and Markakis are positive members of the roster. They are among the least analytical teams in the modern game, and I am confident they don't value defense properly. There is probably some young kid in the analytics department who is being ignored by the good ol' boys club when he points out the same issues we talk about here daily.
If this wasn't the case, Kemp wouldn't play every inning in LF. If they understood defensive value, Simmons would still be on this team. Freeman would not be playing 3B even temporarily since they would realize no other MLB team would be fooled into thinking Freeman was a real option at 3B as leverage to increase Adams' trade value. If they understood the value of defense, the HO trade would have never happened because they would have scouted his recent work at 3B if they saw defense as a priority.
Kemp in LF can work in 2018, but they need to limit his innings in LF aggressively. They can EASILY reduce the number of innings he runs around out there by 10%-20% at a cost of ~5% fewer PAs just by pinch running for him or putting in a defensive substitution in LF after his 4th AB of most games. They need to be proactive and do this from day 1 to keep his legs healthy rather than wait for the nagging injuries to force him to take time off.
The fact they have failed to do this should be alarming to Braves fans. It shows a complete and utter lack of player valuation skill by this FO.
Call me negi all you want, but I see no way the FO can be defended in its utilization of Matt Kemp.
