He coulda been a major player if WWE booking wasn't such a joke. I remember at the time he started, MVP was currently in negotiations with WWE on a contract and constantly referring to his agent. The E should have had Monty Brown play as MVP's agent for his first gimmick, more like his agent/goon.
It was out of WWE's hands. His sister died and he had to take care of her kids. I'm sure he would have been at least ECW champion if he had stuck around.
