There is no other way for SmackDown! to be ran, no matter who is put in that position. It feels good to not see Teddy Long in charge, putting tag team matches together every week, but it' still happening with Booker. WWE has kept that pattern constant because they are concentrated on putting everything into Raw. I thought Booker T would have more freedom, but it never matters who's running the show because Orton's not gonna get the creative attention, ever. It would be nice for someone else to have the job and actually makes it different. I remember back in, 2007 was it? When Vickie was first put in charge of SmackDown! as GM? and she put a triple threat for the Cruiserweight Championship that night, and it was a real nice breathe of fresh air, that's the only thing i remember of that night because Cruiserweights were used to be squashed ever week, one match a week to be squashed. That was something different. Sadly, it won't happen again.
You could make anyone GM, but they won't have no creative control, they just announce the tag matches creative throws together to get the show out of the way so they can concentrate on what Cena's gonna do for 5 months in advance.
