Even if Kerry has his frayed labrum surgically repaired, if he maintains the same delivery won't it just become frayed again? Isn't it logical that the labrum was frayed because of the repeated motion of his delivery? I guess a proper analogy would be is if you had a piece of rope resting against the corner of a building and you kept pulling that rope back and forth eventually you will fray the rope and if you repeat the process long enough it will tear completely. Let's equate surgery to replacing the rope with a brand new one. If you take that new rope and still apply the same exact motion as before, aren't you going to fray that new rope too and eventually tear it apart?
