There is something about that. Nolan Ryan never had arm problems. He threw 90% fastballs.
I think organizations are better off when their guys blow their arms out in the minors. That way they can keep control of the pitchers without having them go through basically 2 years before they are ready to pitch again. Keep them in the minors until they are 25 and let them walk as a free agent. Who knows? I certainly don't, and I'm certain Al Avila has no clue either.
Maybe have a few guys that don't throw as hard but can change speeds well and have great control? Would Greg Maddux even get a shot nowadays?
