umm it's very simple. It's not all about the wrestling, it's about the "it" factor and the personality. What personality does Justin Gabriel have??? exactly, the audience knows nothing about him besides that he has a good looking face and a nice finisher, those will not take you far in WWE, you may think it will but it won't. His mic skils are crap, thats the reason he rarely speaks, flowers in Africa???? really, thats embarassing. And also, "it" factor does not mean you have to be good looking, it means theirs something unique about you that people can connect with
Heath slater has a good personality and decent wrestling skills but he doesn't have the "It" factor, most people find him annoying
David Otunga is almost the total package, his mic skills are amazing, he's always entertaining in that department. He has a great personality, has the "It" factor and he knows how to get heel heat. His wrestling skills may not be good but he can improve, you can't improve "It" factor, either you have it or you don't
