The current storyline where The Miz is being pushed as the “next Ric Flair” was originally earmarked for Dolph Ziggler. With Ziggler, the idea was going to be more of Flair being his manager but Ziggler was going to be given the Figure Four and doing the same gimmick Miz is doing as a babyface.
Regarding turning Ziggler babyface, it looks like those plans have been put on hold for the time being.

Pretty sure Miz won't hold it too long...
