I am probably one of the only few on here, but personally I don't see Daniel Bryan walking out of mania with anything other then a bunch of fans having sympathy for him because he lost to Batista and Orton. Now I'm not a Daniel Bryan hater, but I'm certainly not someone who's jumping on the Bryan bandwagon...here's how mania with Bryan will go, he will defeat Triple H (as planned from the start) then he will be inserted into the title picture because the fans weren't satisfied with the original match and cried like the IWC babies they are, then he will LOSE in some cheap fashion to Batista. This will conclude mania, it gives the fans what they want, Daniel Bryan in the main event, but it also reminds them that WWE is in control, not the WWE Universe.
Bryan will complain the next night on Raw and the Authority will get a ton of heat, then Batista and Bryan will face off at extreme rules where Bryan will win the gold and celebrate with the fans, Bryan shouldn't win the title at all, he's a great guy, hell of a wrestler, but what's left after he wins? Bryan's character is a popular as he is because of his underdog persona, (yes he has his wrestling ability but how far did that get him before the yes chants?) once all this Bryan bandwagon stuff dies down the fans will move on to the next project (Bray, Regins) don't believe me? Ask Ryback, Ryder, Fandango,.
This is one of the stupidest things I've ever read in my life. First of all, the plan from the start was Triple H vs. CM Punk and Randy Orton vs. Batista vs. Daniel Bryan for the WWE WHC title. Why the hell would they build up the CM Punk/Triple H rivalry just to throw it away and make Triple H vs. Daniel Bryan instead? What were they going to do with CM Punk? Punk was feuding with The Authority, we saw it starting with his feud with Kane, and then they just inserted Daniel Bryan into that once Punk left. That seriously makes no sense whatsoever. Of all the idiotic comments about Bryan not being planned to be in the title match originally, that's probably the most moronic of all.
Secondly, if they're going to give Daniel Bryan the title, why the hell would do they it at Extreme Rules instead of WrestleMania? Have 12,000 fans chanting "Yes!" with him instead of 70,000? One of the most memorable moments ever at some no name PPV instead of the granddaddy of them all? Can you imagine Ultimate Warrior beating Hulk Hogan at SummerSlam after losing at WrestleMania VI? Can you imagine Bret Hart beating Yokozuna at King Of The Ring after losing at WrestleMania X? Can you imagine Shawn Michaels beating Bret Hart at In Your House after losing at WrestleMania XII? Can you imagine Steve Austin beating Shawn Michaels at Unforgiven after losing at WrestleMania XIV? Can you imagine Chris Benoit beating Triple H or Shawn Michaels at Backlash after losing at WrestleMania XX? Can you imagine Batista beating Triple H at Backlash after losing at WrestleMania 21? Can you imgine Rey Mysterio beating Randy Orton or Kurt Angle at Judgment Day after losing at WrestleMania 22? None of these things happened, because they're all stupid. That's just some of the title matches, there are plenty of non-title matches outside of the main events where the same thing applies. (And if you think Bryan winning the title isn't as big as those moments, you simply haven't been paying attention.) WrestleMania isn't the show to advance storylines and make people tune in the next night on Raw or buy the next PPV. The entire year revolves around WrestleMania, that's where all the big moments happen.
What you're describing, a face losing to a heel at WrestleMania and then winning the title afterwards, has happened exactly once in the history of WrestleMania. WrestleMania 2000, Triple H retained the title in a fatal fourway against Mick Foley, Big Show, and The Rock(who had Vince turn on him, costing him the match) and then The Rock beat Triple H for the title the next month. And I think most people would universally agree everything about this was stupid. If WWE could go back and redo it, they would have The Rock win the title, probably in a one on one match with Triple H, at WrestleMania.
And I hate to break it to you, but your foolishly short sighted argument that there's nothing left for him to do after he wins the title can be applied to hundreds of underdogs in the history of pro wrestling. What's left is he'll have a nice little run with the title, lose it, and go back to chasing it. If/when the crowd loses interest, he'll eventually stop chasing it. That has absolutely nothing to do with what should happen at Mania, and it just shows your bias against him.
...and what the hell do Ryback, Ryder, or Fandango have to do with Bryan? None of them were remotely close to as over him, nor were they popular as long as him, nor are they as talented as him. Again, your bias is showing.
