Allen Iverson decides to present himself at a postgame news conference as if he were a thug, dressed like an extra in a rap video. His appearance doesn't hinder his play on the court, which is all the naive champs of anything-goes, such as Le Batard, seem to care about. Professional sports leagues, mindful of how they are seen, have every right and obligation to take care with their image. It is buying his behavior, the public image he portrays. Legislating appearance in sports is nothing new.
Some coaches insist players wear suits on road trips.
Others decry facial hair. Athletes enjoy considerable personal time and the freedoms only exorbitant wealth can bring. Nobody can insist an athlete be a positive role model if the role doesn't interest him. Allen Iverson is free to dress as he wishes on his own time. Not a pimp in a Dr. Dre video.
