Do you watch hockey? Almost every team has an enforcer - the guy whose job it is to go out on the ice and fight so that the star players don't have to. Often, they're popular with the fans. Nobody looked at Rob Ray's one goal per year and said he was a failure - his job was to rack up the penalty minutes, and if he had less than 200 in a year, you started to wonder.
Regardless, now it's done. We don't have to debate about what will happen when there's an openly gay guy in professional sports. In a perfect world, we wouldn't have to, but it's not a perfect world.
