#4 Vince McMahon
The more Vince McMahon tries to push Reigns as the company's top guuy, the more he damages his legacy in the process. In fact, The WWE Universe has already made it known that they believe McMahon is out of touch with what fans want and his decison to continue to push Roman Reigns is only going to solidify that.
Not only does McMahon's controversial decison show that McMahon doesn't know what fans want anymore, it also shows that he is more then willing to put the company in jeopardy in order to pusch one guy, which is an extremely dangerous mindset for any business man and could leave the company in shambles as a result.
In the end, McMahon has doen a lot of things to tarnish his legacy in the company, but pushing Roman Reigns after fans basically begging him not to will no doubt go down as the worst thing he's done in his career. Of course McMahon has the chance to rectify this by giving the top slot to someone else, but its seems like he's not interested in doing that.
