Cruiserweight is way too big and 168 is too crowded for him to get a title shot. He should retire but if not I'd like to see him fight the winner of Chavez Jr-Martinez. He called out Martinez before for a catchweight fight but I don't think he pursued it too much. It's unlikely but I'd like to see him fight either of those guys.
he can beat cleverly, bute, froch and cloud. either of those fights at 175 and pray that haye can dethrone at least vitali and then challenge him for a hw title.
