Being an athlete in Georgia is tough on the joints
But the rap musics have led me to believe it's fairly easy to have joints in Georgia.
Starting to think Leo was right about that weird throwing program....
(1) Glavine, Smoltz, and Maddux were all exemplary athletes. I think Medlen is a good athlete as well, but as good as Leo may or may not have been, he was blessed with supremely athletic pitchers. And let's remember that Millwood, Smoltz, and Pete Smith all had arm troubles--not necessarily Tommy John--while under Leo's tutelage. Maddux and Glavine weren't power pitchers, so the leverage issue didn't apply as much to them as it did to the other guys.
Smoltz was a special case, compared with Glavine and Maddux. He threw harder and the slider put greater stress on the elbow joint. Just read his book. FWIW, he disagrees with the pitch count and innings limit trend. Nobody wanted to discuss the topic at Scout in my thread on the subject. My purpose was to consider the possibility that pitch counts and innings limits were contibuting to the increase of pitchers (especially younger ones) to DL time. Arm strength isn't being built up properly by adequate thowing sessions between starts.
Maddux was an early adaptor of the 6 innings and turn it over to the pen. Starters now get paid more for doing less.
Medlen has a few things working against him and his height certainly is a big one. What you described often happens in shorter guys. Kimbrel's gonna have arm issues at some point for similar reasons.
Generally when you're taller you put less effort into velocity.
That and arm angle. Three or four inches of height added to three or four inches of arm length create a release point where the pitch's trajectory can be in the lower part of the strike zone with less arm strain.
