categorically disagree. they've not done a lot with Drew since bringing him back, but that goes both ways. He's not had big moments or wins, but he has been protected, they clearly have always had a vision for him. He got a bit lost in the midcard for a while there, especially when he was one of the Corbin lackeys in that dreadful feud with Rollins, but even then he was a protected guy. I do not think it's correct to say that he was already defined as a guy who would never main event - much the opposite, I think it was clear to anybody paying attention that they had main event aspirations for him.
There was that time last summer when he lost to Roman right after Shane PINNED Roman, but Shane is a cut above I guess ---
