His career is young, so perhaps he is one of the few players who will turn out to be able to sustain a batting average on balls in play (BABIP) at .340 like he had in 2022. They exist (Goldschmidt, Yelich, Judge, Trout, to name some prominent ones) Otherwise he seems like a candidate for regression to a lower level of offensive output, and I would not bank on him being anything close to our best performing outfielder in 2023.
I want to like Gordon, and I do like him, and I'll own up to being slow to rate him as a major leaguer, but I still hold some skepticism on him being more than a role player for the long term.
