#2 Having the wrong guy win
What was WWE thinking?
While some might see it as a great move on WWE's part, Mustafa Ali pinning Daniel Bryan in the main event of Smackdown Live was nothing short of pandering. Beyond that, WWE just handed their company's champion a loss to a guy that has been on the main roster all of one day and has next to zero chance of capitalizing off this.
Sure, he might get a James Ellsworth style role where he comes close one or two times to Daniel Bryan's championship, but those that think he will actually be successful are downright looney. Furthermore, anyone who thinks Ali's win is going to be the start of something big is just downright diluting himself.
This doesn't mean that Ali doesn't have a lot of upsides and is undeserving of the main roster spot he just received, but there's not much they can do with him now. Compare that to someone like Shinsuke Nakamura or Samoa Joe beating him for the title and you start to see the difference in potential.
In the end, Ali will rise in the short term and might even go after a midcard title or two, but it wouldn't be the same if someone like Nakamura, Joe, or even Cien Almas beat him. The point is, there is a lot more they can do with an already established name versus a guy they just pulled from 205 Live
