Fielding percentage in isolation tells us very little, that's for sure.
My issue is that just because fielding percentage by itself tells us little, and just because errors can be a matter of opinion, it still doesn't follow that errors are a meaningless statistic.
One of the biggest issues with Devers as a fielder was...he made too many errors.
Probably the biggest issue with Kike at SS in 2023 was...he made too many errors.
Don't throw out the baby with the bathwater.
