It wasn’t until the late ’90s that NBA players started tatting themselves up. Dennis Rodman, perhaps the baddest boy in league history, was really the first to show off his ink, while Allen Iverson helped make it cool and bring it to the mainstream. Of course, the perception of tattoos has changed drastically since that time. While they were once generally seen as trashy, they’re now considered to be stylish and a vehicle for self-expression. In fact, tattoos have become so popular among NBAers in today’s league that it’s almost more surprising when players don’t have them.
