The sneeze analogy perfectly illustrates what I've been trying to explain. People sneeze all the darn time, and nothing comes of it. Just like as dextermorgan has explained, professional baseball players step awkwardly on their leg all the darn time, and nothing comes of it. So if throwing your back out sneezing is a freak injury (since you've sneezed countless times with no injury occurring), then by the same logic, tearing your ACL stepping awkwardly is also a freak injury (since you've stepped awkwardly countless times with no injury occurring). Except people almost never get hurt sneezing. That's why it's a freak injury. People get hurt by twisting their legs. You're leaving out that very huge difference. Also, I'd say that there's a pretty big difference between a sneeze and a twisting of your leg. One is a natural thing that the body does by itself. The other is something that your body is put through due to a mistake. By your logic, every time a guy suffers a new injury (while doing something he's done hundreds of times before) that he hasn't suffered before, it's a freak injury. I don't see how you find the logic in that. Basically you're saying that freak injuries happen all the time, which pretty much goes against what the definition of what a freak injury is. "Oh Bradley just sprained his MCL while running the bases. He's never done that before. Just a freak injury!" "Oh Bradley just tore his quad while running after a ball in the outfield. He's never done that before. Just a freak injury!" "Oh Bradley just aggravated a muscle in his wrist while taking batting practice. He's never done that before. Just a freak injury!" I think you get the idea.
