Lets create this fictional character. Joe in Topeka. Joe's about 40, hasn't watched Raw in ages, and left his job at the gas station to go to the bar to have a cold one with his buddies, and on the TV he sees an ad for Wrestlemania, and he says to his buddies "Boy howdy, I remember loving that stuff, with the Hulk Hogans and the Ric Flairs and the Macho Mans and the urrrgggghhhh, I've gotta buy it!" Would Joe be more interested in seeing Batista vs Orton in that ad, or Bryan vs anyone? Probably the bigger guys, that's why they're going with Batista and Orton.
As wrestling fans, we should just give up on the concept of Wrestlemania. It's easy to get caught up in the spectacle and the grandeur of the whole thing, but they know it's a cash grab that random people will buy every year and they'll want to capitalize and attract however many random people they can get. We have the Raw after Mania and even Extreme Rules that we can be happy about. So when thinking about it more, I don't think it's that they don't think Bryan is a draw, it's more about getting Joe interested. And your point is sadly pretty valid when it comes to that, Crayo.
Anyway, right now I think they see him - correctly - as a ratings draw (since he seems to always main-event Raw) but not so much of a PPV draw. The only way they can draw buys is having kids nag their parents to shell out $50, for most of us it's too much to ask with a stream being a few clicks away. But the Network should change everything. The Network is basically an IWC dream - getting classic and current wrestling content on the go for 10 bucks - so keeping the wrestling fans happy becomes much better for business than it ever was before. Daniel Bryan and other guys who are actually relevant in 2014 getting the ball and running with it equal Network buys from "smart fans" who are actually smart.
TL/DR: For random people, yes. Weather the WM storm and see what happens.
