Do you have a problem with what he does when he takes the field?
Look, there are Sox players I was never personally fond of but if I have to judge performance I have to concede the truth. Wade Boggs, Roger Clemens, Manny Ramirez, and Pedro Martinez played great baseball for the Boston Red Sox. I personally did not really like any of them at all. But baseball is a selfish sport and rewards selfish behavior. Ted Williams achieved his stated goal to become the greatest hitter who ever lived. He didn't say much about winning championships. The nature of the game is such that if you achieve personal excellence on the field you will help your team win, even if some fans think you are a bad teammate or just a plain old jerk.
