I'd have to look more at his actual matches to weigh in. I don't remember him working tremendously differently in his short hair, Bockwinkel-talking run. I can appreciate reinventions in general, but for the sake of GWE, I'd have to see if he reinvented himself in-ring as much, past the introduction of new finishers over the years. I still get the sense that he does what he's always done and tries to reach for physical spots that are slightly beyond his ability to hit, which was always noticeable but might even be more so as he's gotten older and put on more mass and what he can do has been more and more limited.
