I was initially against the possibility of Kane feuding with Daniel Bryan once Team Hell No went belly up. However, with talk of Kane potentially running for a Senate seat for the 2016 election, my mind may have changed. If Kane is indeed serious about running for political office, then I think he'll be done with WWE sometime in the relatively near future. It'll take time for Glen Jacobs, better known to us as Kane, to build up his reputation as someone that could be viewed as a serious political force. As a result, Kane will certainly have to put the WWE and wrestling in and of itself in the rearview mirror, at least for quite some time. Again, if Jacobs is serious about all this political hoop-la, his wrestling career is something that political opponents will almost certainly attempt to use as a means of painting him in a negative light. Even though 3 years sounds like quite a bit of time, it's really not when it comes to politics. He'll have to organize his campaign, do all sorts of meet & greets with potential supporters & political contributors, truly let it be known where he stands politically and, of course, work on his public image in order to set himself up as Glen Jacobs rather than merely just a former pro wrestler. All that stuff is going to take time and before he knows it, it'll be election time.
I'd like to see Kane ultimately put someone over in a major way. Kane's star isn't on the level of guys like HBK, Rock, Stone Cold, Cena, Orton or Taker. He's someone that's known & respected by fans & insiders but he's not so big that a massive droves of people will come out in force to see him wrestle his last match. I mentioned Daniel Bryan as a potential final feud for Kane IF he decides to leave in the near future. They've got great chemistry with each other and frankly the matches would be worth seeing. Kane could possibly continue his feud against The Shield with or without Bryan. I read a few weeks ago that there's talk of POSSIBLY having the Brothers of Destruction reunite to take on The Shield at SummerSlam.
Currently on the roster; wrestlers like Dolph Ziggler, Daniel Bryan, any member of The Shield, Fandango, Antonio Cesaro, Wade Barrett and a few others could potentially gain a great rub from being Kane's last opponent. If WWE plans to bring up some wrestlers from NXT, then I could also see someone along the lines of Bray Wyatt or Kassius Ohno benefitting from going over someone of Kane's stature and be responsible for "ridding" WWE of the Big Red Monster/Machine.
