Who else is going to challenge for the title? There's only four credible challengers at this point in time for Bryan's title. Orton, Batista, Triple H, and Kane. Cesaro, Ziggler, Sandow, and all the others are just plain not ready. It makes sense for Bryan to keep feuding with the authority, and as time goes on you start to introduce new names into the mix. With a few months build, Cesaro will be a fantastic contender. I think if they reinvest in Sandow, he could no doubt be a real contender. Fact of the matter is, they don't have many options. Kane can still go. He's as good as he's ever been in the ring. And in the almost 20 years (including pre-Kane Glenn Jacobs characters) that he's been around, I don;t think he's ever been out injured. He's a very good hand to keep around, and is useful in drawing money. WWE only has a few options, and since Evolution is facing The Shield, and CM Punk ain't coming back anytime soon, there's only one choice, and it's a perfectly fine choice to make. And that's Kane.
