I have mad respect for Cena, but the reality is wrestling is not big enough anymore to rely on one person becoming a huge star. It's true, to an extent, to say Triple H's approach to NXT won't make Raw way better, but Triple H's approach to NXT - that is, making the card somewhat interesting from top to bottom - will be more consistent, in the long run, financially. Sami Zayn probably won't sell out arenas, but he'd be just fine as a top face for a while if he were buoyed by moderate money makers in the midcard, and if the show, itself, were consistent enough to be worth watching even in the absence of an Austin/Hogan/Cena-tier star.
