I think he has a chance. He style to really mess with Arguello, but ultimately I think he'd lose. Arguello is too reliable to come in at his best and lose to Mitchell, but it wouldn't be an easy fight.
Mitchell would give Arguello all kinds of issues, being a solid operator himself. But I don’t think he would be able to beat Arguello down the stretch. Mitchell is a very tough customer so I see him lasting the distance with Arguello.
I mean, I don't think it's a given that Mitchell goes the distance. He never really faced a big hitter, much less one of the greatest punchers in history. Arguello could very well stop him. I actually suspect he would.
