Looks bad now, but at the time, I didn’t hate it. As I figured he’d be a great center fielder for 100 games a year and average to modestly above average hitter. (I too was apparently overly optimistic.)
But, to your point, Buxton has really NEVER had a good season. The only thing that could be called a ‘season’ was 2017, and only his defense was good that season. His entire career is a string of small sample results…including small sample ‘seasons’…ricocheting between phenomenal and completely awful…great when fly balls are going over the fence, and really bad when they aren’t. Making him what he’s always been…a dangerous, but overall only slightly above average hitter. The K’s and very low OBP were there from day 1, and have always been there.
