The only thing I have noticed about Sale since he has been here is that if he is not blowing hitters away, his confidence in himself seems to diminish so much so that it effects his game. He does not appear to let a bad call effect him, an error by a teammate, any of that sort of stuff. But so much of his makeup is built around complete dominance that just plain dominance seems to bug him. For example, I always thought this whole thing of not shaking off anything was BS. "Doesn't matter what pitch is called, I am going to dominate with it". My ass.
Anyway its his own confidence in himself that seems too easily shaken to me. He is a great pitcher and he does not have to dominate every hitter completely to prove that...not to me anyway. He does seem to need it to prove it to himself. You can see the confidence leaking out of him just because he is not blowing hitters completely away. Its between his ears, which is not unusual for the modern day pitcher anyway.
