Yes, that is the answer, jettison actual knowledge for gut feelings.
There's a lot of data that back up 28 being the prime of a baseball player's career, experience and athleticism crossing on separate paths. I'm certainly not saying "yawn" to the time after 30, or calling players under 26 rushed.
In the conversation about whether Robert still has the ceiling of his 2023 season, or whether he's now the stats he's put up in the last two seasons, it's not crazy to notice that the upcoming season is his "prime", and if Robert has any upside left, it's in the next year or so he'll have youthful athleticism to pursue it.
As far as the Pete Rose part, analytics loved him. I'm not sure how the actual events that get analyzed would "mean nothing". Maybe you should read up on analytics, and you'd learn that BA, OBP and base running are all factored into WAR and RC+. He might have even won more than one MVP and made more money had he paid closer attention to his own trend lines.
