The fan obsession with E-rod's "body language" or "lack of emotion" says more about fandom than athletics. Not every athlete has to charge into the dugout in rage after a K, throwing bats around and smashing things, a la Keven Youkilis before Manny offered to punch him out for doing it. Getting excited, jumping up and down, pounding one's chest, and screaming is entertaining (and sports is, after all, entertainment), but has absolutely nothing to do with effective performance.
