Miz didnt need the U.S. title anymore when he got that briefcase. He's already in that main level now. He already had a match vs. Orton and one vs. Cena since winning case. And about defending U.S. title; I thought all titles had to be defended at the most once a month. He has not defended it in 3 months! It would not hurt to give it to Daniel Bryan or Ted DiBiase, Jr. or even John Morrison cause obviously Vince still isn't sure about him being the WWE champ.
