The title picture lacks the balance between old and new guys, thats for sure. Since 2009 there havent been many great WWE champions. Maybe if WWE let some of the older guys get involved we wouldnt have had the back to back Cena title reigns. I still think The Undertaker is needed at a much more limited role. Not a full on rivalry but the presence of the Deadman could boost a match like the Elimination Chamber to the next level. Although hes a bit more slower hes still great in the ring and I think that if WWE reduced his matches to the absolutely necessary he wouldnt be suffering so many injuries. I guess it doesnt matter now since his career is almost over, but theres no doubt Taker could help some ppv card become a little stronger.
