WWE can easily push MVP's character. Hell, with the correct booking, and I'm sure Michael Hayes could, they could turn the losing streak into a huge push.
However, he is not the future. He's 35 years old, and imo, he'll never be able to get over Orton, Edge and Cena, who are younger and way more over.
Orton, Cena and Edge will be the go to guys. Edge still has a couple of years in him, 5 if not 10 years more. Orton has been around forever and he's not even 30 I think, same for Cena.
Watch out for Ted DiBiase. He must already be very well liked on the inside that he got a movie deal in 4 months of being on the roster
