LOL. The guy who took 'roids, despite being one of the best players in the world, so he could be better and did this had the smaller ego.
Yeah, OK. A-Roid moved to 3B, willingly, because he wanted the world to perceive that he was a "team guy". Plus, taking the D responsibility away would allow him to bulk up and, shockingly, hit more homers so he could be the all-time home run king.
