Even if he could be a good face skill-wise he has just become such a shit character it won't work.
Best Corbin is the lone wolf with long hair and his proper entrance music, his look was decent then and he's honestly not bad in the ring as a powerhouse.
Giving him these heavy talking characters is so far from his wheelhouse it's crazy.
I wouldn't be surprised to see Corbin out of the company in the next few years, I just can't see how the character can be redeemed. And there are many other guys who can take over the heel type of roles he has been given coming through NXT - Thatcher, Lumis, Kross etc. Corbin will soon be surplus to requirements, and he won't work in the jobber role like other WWE nobodies.
