If he showed up at the Rumble, no one would know who he is lol.I'd respect him more if he stopped flying around so much. Save that type of shit for special occasions! Work a real big man style with maybe a big man top rope splash here and there. However, I think he could be something special with new attire as well. He looks like an action figure. Cage has a good look, "too roided" looking at times, but if he cuts back on the juice, he can look less freakishly bad.
I really can't stand the independent name he has been using. The last name Cage isn't bad, but I really think a first name change should be in his future should he ever join the WWE. He would be a huge surprise for the Royal Rumble. I am not a huge fan of him, but if he showed up at the Rumble, I'd might mark for him with a new look and name. A part in the Royal Rumble is certainly a way to get a person over with the fans in a short period of time when done properly. This could be a deal breaker for a guy who wasn't much on the independent circuit.
If anything, he deserves a spot at the Royal Rumble. Show the world what he can do on a very big stage. Give him that moment where the fans think he may have a chance, perhaps final 4, or 3 left. Let him eliminate a big name, or two. Give him the spotlight. He might not impress everyone, but he certainly will stand out.
