One way to get a handle on this for hitters is to look for lots of plate appearances young. Here is the list of batters active in 2024 with the most PA through their age 24 season:

Lots of PA early gives batters a chance to build high counting stats over time. It also indicates special talent; these players were so good they could come up early and stay in the lineup.

I would say nine of the nineteen listed here have pretty good Hall of Fame chances. Three of the top four likely made their case already, and Soto doesn’t need to do much more. Freeman, Devers, Betts, Acuna, and Altuve seem likely. Albies might surprise us if he lasts a long time. Even among the ones not likely to make it, there are a few MVPs and lots of big contracts.
