> 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.
Taller players do great in soccer, to a point. I mean, goalkeepers are the tallest, typically, about 6'4, 6'5. For field players, they usually max out around 6'3, but that's only for certain specialized positions like a striker, or central defender. Above that and you are too big and too slow, smaller players will quite literally run circles around you. I think overall average height of soccer player is below 6 feet.
Lionel Messi, the greatest soccer player of all time is only 5'7 - that should tell you something.
