Kevin Kiermaier set an all-time mark of sorts in 2015: The reigning Esurance MLB Best Defensive Player had the top statistical defensive season in recorded history, saving 42 runs with his glove, per Defensive Runs Saved. Obviously, that comes with a pair of enormous caveats. The first is that "recorded history" for DRS goes back only to 2002; the second being that it was his first full season, and we know that the current defensive stats generally require more than a single season to be reliable.
It's a question that vexed me as I put together a list of Top 10 center fielders for a statistically oriented segment on MLB Network's ongoing positional ranking series (Thursday nights, 9 ET). How much stock do you put into that DRS mark? Is it enough to overcome Kiermaier's uncertain offensive profile, particularly a .298 OBP?
