> In soccer your height/mass doesn’t matter much so the talent pools don’t overlap.

This is untrue and also just silly. The talent pools for horse jockeys and NBA players don't overlap. The talent pool for soccer and football is probably 90% overlap. Smaller players are certainly more likely to be successful in soccer than football but tall players can do great in soccer and average height guys can do well in football.

> And baseball is the old man’s game that does not require any athleticism at all.

Come on. Baseball doesn't demand the same athleticism as soccer but these guys are still elite athletes and there are plenty of stories of both MLB and NFL offering positions to the same players.
