Extreme cases almost always blow out their arm.
Randy Johnson is not an exception. He battled arm injuries that kept him ineffective until he was almost 30. He wasn't "the big unit" until age 29. It wasn't until he gained 50 pounds of muscle to his frame that things turned around for him. There isn't anyone in the history of baseball with his physique. No, Chris Sale is not a Randy Johnson clone. You could fit Chris Sale inside Randy Johnson's frame and still have room for another person.
Umm, Randy Johnson struggled with injuries because he didn't know how to pitch, gaining fifty pounds did not magically make him an effective pitcher, learning how to pitch did that.
