Kofi just needs a good singles feud. What he needs is a long and very competitive US title run. Defend it regularly against a quality, proven opponent. Right now I'm guessing a Bourne/Show/Kofi triple threat at NOC, but I don't like that. Wasn't it a little over a month ago at Extreme Rules where he defended the belt in a fatal fourway? He needs what Mysterio needed, but not Jericho specifically. It would be great, but it would take too much switching around to make it believable.
I would like a feud between Kofi and Miz. Miz is a guy who can handle most of the mic work. Miz I think just finished his Cena program for a while and needs something to do. Plus, I could see Miz and Kofi putting on some very good matches. Plus, if Maryse takes the valet role with Miz, it can give him an unclean or two over Kofi and let Kofi chase the belt. I mean if you think about it, Kofi has never fully chased the belt. His first reign was a shocker and his second one, he only did one promo with MVP but that was it. If he lost to Miz at say ... Summerslam and then became the chaser he would be taken a lot more seriously.
