I'll have to disagree with Knicky here, Mr. Kennedy was more than ready for a title, in fact, he was ready for the WHC. And that is because all you said he had it on SD. He came out good with his feud with Taker and fought Batista for the World Title, he then won Money in the Bank. People might say he lost MITB because of his injury, but WWE not only jumped ship but also made the mistake of his life trading him to Raw.
And yeah, his promos are great, but they weren't his only trick. He used them to hype matches with the ones of Rey Mysterio, Batista and Taker. But know, he only repits his name and squashes Super Crazy or the Sandman.
Ok, to end it, Kennedy is ready to be champion, on Smackdown, not quite ready on Raw
