I've heard that John Cena is like the best drawer in history. Particularly with colored pencils, but not shitty Crayola pencils, like good ones from an art store.
No waaaay maaaan, I've seen Jeff Hardy's... stuff...
Yeah, the WWE is a very different beast, not just compared to the territories, but compared to WWE or yore. When I think of the WWE now, I feel like their corporate structure is so much more refined that they are firmly entrenched into their position. I think it would take series of catastrophic events to ever threaten the relative safety of their established market.
Television ratings for the show many be at a low point, but I also think they vary in a much smaller potential range of numbers. Shows can vary greatly, but the ratings do not fluctuate massively, if only noticeably and definably when a big star returns, expressed as an anomalous spike.
And I don't think Cena is a crutch for the WWE much now. He still moves merch by the boat-load, even when he's not the focus of the show because his success in the younger (and to a lesser extent, the female) demographics is so firmly entrenched. But I don't think he's as important now as he was in 2008, say, when he really was the overriding steadfast paragon of the organization. Now, he IS, as Punk so brilliantly put it, "the establishment", and he's the target for guys to aim for. And many guys have come through to take that shot. Cena is only getting older, he can't be made any bigger a star than he is now at the behest of The Rock's continued Wrestlemania presence. But Daniel Bryan, Roman Reigns (for whom the stars are all but aligning), Dean Ambrose, Bray Wyatt, Seth Rollins, in that order, are threatening competently for that coveted spot, and soon enough he'll have to relinquish. And none of it will make a big difference to the ratings.
When you talk about how a guy draws these days, you really need to look much more at merchandise, unadulterated crowd reactions and gates of major PPVs (which are bastardised somewhat anyway by storylines), and then you need to compare that to other superstars as there is no other comparison for the WWE, except for maybe itself and it's stars of the last five or so years. I'm sure he's drawn a crazy amount for the WWE in revenue, but it's hard to really say what that amounts to, even when trying to compare to Rock or Austin of 15 years ago. The company is different, the structure is different, the ratings are less volatile.
