#3 Tyler Bate
Selfishly I really want Tyler to succeed because England really needs his first world champion. But if anyone from anywhere in the world watches him it is undeniable that he has the potential to be WWE champion one day.
And he is only 22! WWE could wait 10 or 15 years to call him up and he could still become champion if given the chance. With the talent that he has, it seems impossible that he won't one day be WWE champion.
#2 Velveteen Dream
This is one you maybe saw coming. Velveteen Dream has become one of NXT's biggest stars in the last year at the young age of 23. He has been praised by ever superstar under the sun including John Cena who knows a little bit about what it takes to become a champion in WWE.
His character does compare to someone like Goldust who didn't quite make it to the top of the WWE ladder. But no one on the current full-time roster is anything like Dream so if handled right by Vince could not just become WWE champion, but one of WWE's biggest stars.
