Chuck hasnt fought anybody that will come forward continuously like Wandy will, and it'll take alot for Chuck to beat him. I think that he has improved considerably in the last 3 years, and i think he has an excellent chance of winning but it wont be a 1 way fight. Wandy has every tool in the bag to beat someone, he will just knee the shit out of you until you cant lift your arms, and then just keep doing it for fun. Chuck would have to be over twice the fighter he was against Randy to beat Wandy. I want to say Chuck for the win, but theres always a naggig doubt because of who Wandy is.
I just hope the fight happens one day whilst theyre both still at their respective best to settle this once and for all
