Describe one way that Milton Bradley's presence on the Cubs roster would affect Lee's ability to hit (I seem to recall he hit pretty good this year), pitch/catch or run. Describe one way that a professional athlete making millions of dollars would allow their hatred for a teammate to affect his play on the field. Just one. Well "by committing murder" has been nominated. So has "by committing rape". Those seem just as silly to me as "by acting like a jerk". You think it's silly to not want to cheer on a rapist? Most ballplayers are jerks, very few are convicted rapists or murderers.
