Right now, dirrell would have the best chance

Look at timing too, where the fights are taking place and the schedule i have given you above (not unlike froch's)

If that schedule was planned for ward and you went to a bookies and put a pound on him to win every fight, if it came in you would be a rich man

If you put the same pound on him to lose at least 1 of those fights you might get 50p back if you are lucky
