Right now when it comes to power and making decisions within WWE, there are a lot of people involved in the process but the only real key decision makers are Vince McMahon and Triple H.
Regarding everything changing on Mondays, RAW is WWE’s big priority and as of late, they don’t even start talking about what they are going to do on SmackDown until Monday afternoon. Then around 6pm, Vince will want the writing team to give him a SmackDown main event so it can be promoted on RAW, and then the writers start scrambling for a match. This is why SmackDown and Main Event matches on RAW frequently change.
The reason this week’s CM Punk vs. a member of The Shield match was promoted is because as of around 10pm on Monday night, Vince still hadn’t made up his mind on which of the three Shield members would best fit as Punk’s opponent.
Regarding Daniel Bryan’s recent push, it’s not that creative didn’t want him to get revenge, a WWE Title win or even some kind of symbolic win, it’s that nobody else really has the kind of influence except Vince and Triple H.
