When you break a man's ankle with steel steps, you know he's going to come back and whip your ass. The idea of Kane and Seth Rollins at Hell in a Cell could be a lot of fun. Presume that Rollins' rematch with John Cena ends when Rollins is going for a Pedigree, and the lights go out. When the lights come back on, there's the Big Red Machine, back in his mask, brutalizing Rollins. Babyface Kane versus heel Rollins isn't a Wrestlemania-level feud, but given the talent of both of the performers, it's entirely possible that this would be a great placeholder rivalry to keep Rollins hot without the championship.
