Smith is an antagonist who is all over the map, honestly he is worse than Bummy.
Carr on the other hand may just be an idiot. So I see the match unfolding this way: The two will meet in the octagon, Carr will punch Smith in the face before the reff even has a chance to give instructions and knock him cold. Carr will then bolt from the arena and blame the escape on his offensive line which was unable to protect him. Smith will be declared the winner by default. Then Gruden will step in and say 'I told him to run "Spider Y Banana, instead he just punched the guy and ran. This is why Carr doesn't understand the offense."
Carr will respond that he believes that the Patriots stole his playbook and the Belichick is "A Bad Man"
