I think that poster probably meant Jacoby Jones, the football player.
My feelings about Dorothy's dances: her first one, the contemporary one, clearly showed talent and musicality, whereas Lisa is stiff and still a bit clueless. Dorothy's second dance was hampered by her injury. Additionally, a large proportion of a celebrity's longevity comes from popularity. You know that skate fans voted for Dorothy! Ah, well; it was not to be.
