#2 Big Cass

He may be out with injury for the time being but Big Cass has been touted as a future WWE Champion - and with good reason.
He's quite passable in the ring, can certainly work a microphone and.... Well, he's seven feet tall so I guess that pretty much takes precedence over everything else in Vince McMahon's eyes.
Cody Rhodes' uncle is a WWE Hall of Famer. More details HERE.
But all in all, Cass is quite over with the WWE Universe, especially after the whole episode with Enzo Amore.
And giving him a run in the main event scene when he returns, especially if he's transferred over to the Blue brand, could work out favourably for all parties involved.
SmackDown Live needs new faces to head up the brand after John Cena has semi-retired and Big Cass could do with the opportunity.
