If you threw a football with the same delivery, arm action and intensity as a pitcher your arm would last about 2 starts before you blew it out. The point is: It (the football) is a different object, with a different, less stressful, less max effort, less load delivery. Additionally, it is a different shape & yes, it weighs more.
So, you're saying you can throw the heavy object - just not the way a baseball is traditionally pitched?
Perhaps by throwing the heavy object, the body learns how to perform the throwing motion in a safer manner, and becomes conditioned to do so.
- of course the pitchers could just keep doing the same thing the same way they have always done it.
By the way, the Earth is flat. I've seen the pictures.
