Now that Cena is gone, it's a great opportunity for WWE to concentrate of building up their younger stars and molding in future "franchise players" or "faces of their company". A lot of potential wrestlers that can take the reigns of Cena's "franchise player" position, and we could possibly have another Attitude Era like group of franchise players (if the WWE plays the cards right).
I'm happy to see Del Rio back in the WWE, he's a great wrestler. Is Reigns ready to reign? Hell yeah i think he is... compared to last year. He has proven himself after going through a brutal Hell in a Cell matchup. He is eventually gonna a champion for long term, but obviously Sheamus is gonna cash in along the way.
I personally don't care much about this Wyatt/Taker feud, as it already happened last year. It's not longer fresh. Plus even Taker can still pack a punch, it's not the same. If this was the 2004 or 2007 Undertaker, when he was active full-time, I'd enjoy the match up more. Bringing Kane into the fold is nothing new either, it was Kane who first feuded with The Wyatt after all.
