Glen Johnson has been screwed over more times than most people, but I dont think it has affected him that badly. He has continued getting big fights, in which he in turn has done himself well, and at the end of his career, he is being held in very high esteem. Would he be anywhere else now, had he got the nod against Woods for example?

Anyway, the ones who are really badly affected by bad decisions are those who fight the fight of their lives, against opposition who are better (or more famous) than them, wins, but gets screwed and therefore has to settle for forever being journeymen, never really tasting that sweet glory, money and fame, they actually came within one bad decision of reaching. Santa Cruz-Casamayor comes to mind.
