Those are just a few. But I agree, he is very dull and lifeless. Has zero charisma unlike Eddie who was full of it. He's not a bad worker but he has literally the worst frog splash I've ever seen. As long as he stays midcard then I don't see him as a big problem.
Chavo has been a solid worker. The guy did some decent stuff in WcW but all the later fans remember is the crap he had to do in WWE. Not to mention hes not just not the worse worker in TNA , he is also not the worst in his own damn tag team.
