Excuse me while I get this thread back on topic
The writers obviously realized the Jamaican Kofi character was one dimensional and it had no future. To try and alleviate the problem, they just made him an African guy so he can cut normal promos and drop the accent. Sometimes things like this happen in wrestling, and the writers just can't figure out an angle to justify the change, so they just do it and hope the viewers don't care (Russo's done this his entire career).
So, in short, I guess it doesn't really matter that they just changed him from a Jamaican to an African, because the creative team probably had no idea how to justify it on TV. As far as Kofi is concerned, I have no problem with him as a depth midcard babyface but I see him going no higher than that. Although he got over in his feud with Orton, I just don't see the potential other people do. He'll replace Shelton in the "midcarder for life" role.
