I don't quite understand what "cherry picked risk factor" is getting at, but I am certainly not saying that height will cause injury.
Compare Brandon Webb's pitching motion to that of a smaller guy like Lincecum and you will see what I am talking about. The process is much more isolated to certain muscles of the body. Pitching is inherently a risk through its nature, there are only risky mechanics and riskier mechanics. I think we are talking about two different things though. I am not considering success rate at all. Pitching mechanics and height make up two small parts of many that contribute to the success of a pitcher.
