Ok time for some perspective.
A while back you called out moon for referencing 700 plays by saying “no one makes that many plays in a season,” which, first of all, isn’t true. It’s been done ( for example Ozzie Smith made 909 plays in 1980 (621 assists, 288 putouts).
But to call .961 to .958 regression. It’s a difference of 3 errors PER 1,000 CHANCES! And in the minors, where Mayer was playing 600+ innings per year and getting 300-400 chances per year, it takes multiple years to make 1,000 chances. So you’re talking about a different 1 error per year and calling it “regression.”
And a fielding percentage on 70 chances is useless. A single error is worth 0.014. Thats a big change on a single play. There’s a reason guys with 70 at bats don’t qualify for a batting title…
