All ifs and buts.

He needs to either fight and beat Vitali or Vitali to retire right now so Wlad has a chance to win his title and defend all of them. While Vitali is around Wlad isnt the best because they refuse to fight each other. I belive Vitali wins but regardless, that unkown is holding back any real regard or legacy because in the future it will always be questioned because of his brother.
