I don’t think we can quantify greatness in any meaningful way beyond looking at the output of their careers. Josh Gibson, Satchell Paige, they may well be deserving but we cannot know; they have very brief recorded “major league” careers, and talent was not so centered in those leagues as it was in the NL and AL.

RP, C and 3B are the weakest positions most ripe for someone to take over the slots.

Disclaimer: I am cognizant that this is a matter of opinion and not true/false dichotomy, because greatest is a imprecise word we are not defining narrowly by which we could arrive at a total answer within the set parameters. It’s just fun.
