You may remember former Brewer/Rockie Scott Karl. Well, Brewerfan managed to scoop up an interview with Karl, and it’s pretty interesting. You sometimes wonder why and how players start to lose their edge, and Karl provides one example:
…I had developed a genetic condition that limited the elasticity of my ligaments and tendons. I could still throw the ball where I wanted to, and make it move, but my velocity was going, and when that started for me, it went fast. I never had an arm injury in my career, but when that happened, I just lost the velocity.
