Touche! LOL. Aside from "being left handed," A. J. was a very smart player, with a high baseball acumen. He could grate on opposing player's nerves, and I know that he had a reputation of being "one of the most hated players in baseball". If I had to sum up my impression of the difference between the two players, in respect to their character, I would say that A. J. seemed to enjoy playing a villain, but Machado seems to actually be one. With A. J. it was often a "work," in the tradition of Pro Wrestling, something for which he had a fascination. I think he enjoyed the theatrics. By contrast, Machado seems to be serious about being a jerk, at times. At any rate, it's all very subjective.
