But if you look at most current players that hit further to the left, their upper arm is still in line with the shoulder plane at contact, or close to it. The difference is that the shoulders must be tilted more for the upper arm to stay in line. Take a look at Roddick.
So, if this is the case, internal rotation is going to occur at the same angle in relation to shoulder plane, which I think suggests that there wouldn't be much difference, if any, in the amount of stress to the rotator cuff.
If anyone could prove this wrong or add any further information, that would be great.
