I think you guys are confusing innate ability or natural talent with athleticism.
Being athletic doesn't mean you can throw a ball 95 mph, or hit it 400'. These are specific natural talents.
Michael Jordan is an amazing athlete but didn't have the talent to hit a breaking ball. Having a vertical leap of 48" doesn't mean you can throw or hit a baseball well enough to play at a high level.
How many non athletic looking pitchers are in the major leagues, or power hitters for that matter.
Black, white or purple, if you don't have a natural baseball talent chances are you won't make to the top of the baseball world.
