Ok, I'm not sure who you were responding to. But... I cited current-year stats, not career stats.
Yes, Adell had a much better season in 2025... and at age 26, which some SABR types consider the age at which a player is most likely to peak.
So far in 2026, Adell is producing at almost exactly his career averages - pretty much what he did in 2024. (His 2026 'breakout' pretty much washed away his earlier, poorer years.)
Will he rebound to something like what he did last season? Maybe. Will he settle in at something more like his 2024 (and his 2026 first "half")? If the former, he could have some value for a few years. If the latter, he's s below-average (OPS+ of 90 or so) hitting right fielder. That's roughly what Adolis Garcia was last year, although Garcia may have fallen off the age cliff in 2026. Adell is younger, which makes it more likely that he could continue to produce a slightly below-average OPS+, with the possibility of more... whereas Garcia is likely toast.
Would I trade Garcia one-on-one for Adell? Sure. Would I give up anything else of value, for the chance that Adell will do more than his 2024 and partial 2026 output? Not much; certainly not anybody high on our prospects list.
