I think Nunn would outbox G-Man, Nunn was hitable though and McClellans power was undeniable, my money would be on Nunn to pass the first few rounds where Gerald is most dangerous and outbox McClellan the rest of the way
G-Man would either finish second to Nunn, in losing a decision to him, or finish "Second to" Nunn by stopping him... Leaning toward the former.
