Definitely a complex issue. Anecdotal example from the Marlins' outfield - Thin Ichiro and Yelich, Big Ozuna Giant Stanton. All have good arms, but very diverse bodies. Now sure, all those guys are in great shape and very athletic - but then how do you explain Bartolo Colon? He's in his mid 40's, looks like the guy who was always picked last in recess - and he still throws harder than like 99.999 percent of people on the planet.
I suspect sorcery.
