Cesaro
I’m well aware that, at the time of writing, Cesaro is part of one of the hottest tag teams in the WWE right now and has been delivering stellar tag team bouts for the last few months. Sheamus, however, is rumoured to be taking time off very soon and that kind of leaves Cesaro with nothing to do. While feuds with the likes of Elias and Jason Jordan are a possibility for him, matches with the likes of AJ Styles, Kevin Owens and Shinsuke Nakamura are a much more attractive prospect.
Cesaro was fairly vocal about being placed on Raws during the original brand split and his style is much more suited to Tuesday nights. After his run with Sheamus, Cesaro, as a heel or a face, would fit in quite nicely in the US title division on Smackdown.
