I'm curious to see how you would justify that. By basically every metric -- classic or sabermetric or statcast -- he's not been good, let alone "very good". Batting average, slug%, on base%, wOBA, OPS, OPS+, runs, rbi, exit velocity, hard contact rate, barrel%... none of those things are good. Even his stolen base #'s aren't very good.
His defense is pretty good, I will give you that one.
