I could definitely see him winning the IC or US championship at some point before the year is over. Cesaro deserves a long and respectful top-tier championship run more than anybody. He's the best wrestler in WWE right now. If Kevin Owens isn't the one, then Cesaro should be the guy to take the title off Cena.
The only problem is, once Cena loses the mid card championship does he stay in the mid card or end up back in the main event? I think that calls for a separate topic in itself, which I'll take the liberty to post.
