The problem is, outside of coming up with Hulkamania/WrestleMania, nothing that was 100% his (or his idea) has been successful. Let's discuss the following wrestler's Vince tried to build as "the guy" but ultimately failed:

* Diesel. Never caught on and eventually Vince had to drop the title back to Bret
* Luger. LOL, need we go into this? Again, Vince had to let Bret run with it
* Lashley. Had him become the "face" of the ECW brand when the entire WWE universe and the crowd at the December to Dismember PPV wanted Punk. This resulted in Heyman quitting the company and several other wrestlers asking for their release.
* Reigns

To fill in the gaps with the stars who Vince would like you to think were his creation:
* Stone Cold was mix of Austin finding the character and the crowd organically getting behind him. Not Vince's create
* Same goes for The Rock
* Cena? That was Stephanie urging him to take his freestyle rapping backstage and turn it into a character. When did Cena become stale and hated for the wrong reasons? When Vince turned him into Super Cena.

Anybody who organically gets over, without Vince's permission or in spite of Vince's other pet projects, they get cooled off one way or another (jobbed out, put into meaningless fueds or taken off TV entirely) while he continues to try and push his latest musclely monster. He'd rather have his idea fail than somebody else's make him tons of fucking money.
