Well, I have no reason to not like the idea. Kane is like-able, good on the stick, is nearly 7 feet and isn't corny caricature like Seth Rollins.
If I were flipping through the channels and came upon Kane holding the strap I would put down the clicker.
Rollins has no downside, is safe, does everything well and is absolutely gifted in the ring. Great, he's HBK circa 1995 (without the drama).
Provided he remains masked, Kane be an ideal choice to mix things up. Then again, why mix things up when being stale resulted in Vince becoming a billionaire again.
The best part about Kane, in my view, is that the essence of his character is still violent and fiery. I vote yes.
Edit: I'm ready for a babyface champion. WWE is relying too heavily on this heel bullsh*t. Just because Sin Cara was worthless and Kharma got pregnant at the wrong time doesn't mean not to take any risks at all whatsoever. If they really intend to break Punk's record, it shows how truly insecure these nutbags really are. What happens when Nikki Bella bounces? What if Rollins gets into a car accident and somebody else dies as a result?
