Tim did say he was talking about decline based on age. I read it that Zobrist is the only guy who is so old you have to expect decline. He also specified offense. I can't speak for Tim, but I'm sure he'd agree that Baez is also likely to regress, but thats a matter of regression to the mean, not way-past-peak age. I have to say I agree with what he wrote, and think you would too if he expounded. Nope. Especially as it's become more and more clear how early players' peaks are, especially when it comes to offensive output. Nope it's actually becoming less clear and more variable in todays game thanks to players adjusting swings for launch angle, player conditioning and advance scouting .
