The Big Show is an amazing asset for a company to have if they would use him properly instead of booking him like a top guy.
In theory you're right, Big Show does still have a lot to contribute. But lets be real here.
The Big Show and Kane aren't main eventers. They aren't really being used a such, the Authority is just saying "rawr babyface I hate you, here deal with THE DEMON KANE tonight" as a way to use these giants as the roadblocks they are supposed to be used as. It just happens to be in main event segments.
A guy like Daniel Bryan going over a Kane or a Big Show should be a huge deal - in theory, but Kane's been beaten down so much that beating him means dick, so it just leaves the common complaint of shitty matches and terrible ratings. Same with Big Show. Can they really be used as utility guys after being booked into the ground like this?
Speaking of in theory... I was thinking about this at work, and feel free to beg me to "start a new thread u n00b" or whatnot, but want you and Balor to chime in...
What if everything DID go according to plan? What if Daniel Bryan and Roman Reigns never got injured? What if we lived in a world with no hernias or broken necks?
I truly believe this whole plan was concocted BEFORE Wrestlemania 30. That's why the Streak was broken and this Lesnar warpath went on... But what if it was Bryan that got totally buttfucked at Summerslam? Would it have removed Bryan as a possible Rumble winner and made the crowd even more accepting of Reigns's win, or would the inevitability of "the chosen one" get him even more heat?
Add in the Survivor Series match, where Roman Reigns would have got Ziggler's big moment (and looked... pretty badass doing it? Not as much but shhhh we wouldn't know that). He'd be the guy who somewhat ended the Authority so there's more of a reason to cheer him. He would have had more ring time too, which could mean either more experience or more exposure.
Barring the myriad of other dominoes that would have fallen, how would the Fumble at the Rumble changed?
