I guess no one is immune.....from mikeweir.com June 1/11, Mike's blog
"I think it's safe to say that my elbow injury caused me to develop some bad habits and one of those was my fear of going down after the ball. I was sort of anticipating the pain that might occur if I hit the ground and as a result, I started to swing with almost a reverse C, with my weight moving backwards instead of into the ball. I just did this gradually and over time, it just got worse and worse."
