2. Dalton Castle
Despite the fact that his first ROH world title reign was marred by a serious back injury, Castle remains wildly popular among the ROH base. No doubt this is because of his nigh perfect background prior to becoming a wrestler; Castle was a champion greco roman amateur wrestler and a former radio DJ. He knows how to perform, and has all the fundamentals and athletic ability you could ask for in a world champion wrestler.
Castle may not be able to use his over the top homosexual persona in WWE, but no matter what the script we're betting Castle could make it entertaining.
Why WWE needs him: Castle is pound for pound one of the best wrestlers on the planet, capable of holding his own with men like Jay Lethal or Adam Cole. And even when his wrestling days are done, his top-tier charisma would make him an excellent announcer or manager.
