The entire offensive line up of the Baltimore Ravens...

1: Jacoby would sell the hell out of that spinebuster!
Anyway, the easy answer is Bryan, but to make the Bryan comeback effective the earliest you could do that is Extreme Rules.
Strictly from a kayfabe standpoint (obviously), the Big Show thing has been well-built enough to make you want to see Big Show/HHH. But the problem with that is that it feels like SUCH an important match that Big Show/Randy Orton for the WWE Title simply can't compare to it. It's a letdown. I guess this is a case of "wrestling is like a circus, there's something for everyone, when you don't like the elephants you can just watch the acrobats". For storyline's sake we need to get Big Show vs Triple H, and just grin and hope for the best just like we will with the Cena match and enjoy the Wyatt family match as much as possible.
