This the same thing they were doing with Bryan before he got injured; an easy Kane feud. You see how easy Kane got his heat back after nothing for months? That's why he's not gone yet. That's why him, Show and to a lesser extent Henry are going to be around for awhile longer. They haven't built any stars (Lesnar doesn't count) that you can give almost instant credibility to. Stroughman has potential though as does Harper and maybe Rowan as a psycho heel akin to Heidenreich with the outside the ring fukkery.
