#3 Dale Earnhardt Jr
Why is the golden boy on this list? To be blunt, he never lived up to expectations and became an overhyped sideshow that hurt the sport. Not only was that evident by the amount of television time that was devoted to Dale Jr during his Cup Series career, but also by how little the sport recognized other growing stars in that time.
Of course that’s not exactly Jr’s fault an he did eventually carve out a nice little career for himself at in The Cup Series, but the time that was devoted to him was absolutely not necessary. Furthermore, it stunted the growth of other stars that could have taken the sport by storm if given the right opportunity and publicity.
