Nope
1. He's not proven he can wrestle in any capacity. You can't get away with just Goldberg-like squash matches on the main roster
2. He gets no reaction in NXT. If you can't get a reaction in Full Sail, how are you gonna get a reaction from 15,000 people that don't know who you are?
Goldberg when he first started out actually brought intensity and ferocity to his squashes. They were squashes, but they made you pay attention.
Corbin has zero energy in the ring.
Yeah your first thoughts are "Wow, who is that? He is HUGE!"
With Corbin your first thoughts are "He looks bored. Why does he have a second face on his body?"
However Corbin is 6'8". Same height as the mongoloid. He's almost a half foot taller than Roman. If his music hits and Cole goes OH MY GOD IT'S THE SIX FOOT TEN LONE WOLF OF NXT BARON CORBIN...suddenly he's a big person and can combat the mongoloid's size. (and I added a couple inches because, like most men, the WWE can't just tell the size like it is)
I think you're vastly overestimating Cole's ability to sell a crowd. Corbin may be 6'8", but he's still only 2/3 of the black sheep's size.
I'm hoping that Reigns and Ambrose found a partner and found Sister Abigail.
