A prime Tommy Hearns and prime Michael Nunn vs Billy Conn at 168lbs who would have won?

I`m not talking about the Hearns that fought Ray in their rematch, I`m talking about the Hearns that fought Hagler if he had to move up at that stage of hos career to take on Conn at 168lbs during his era also and I`m not talking about when Nunn was a super middle weight champ, I`m talking as though Nunn had just fought Tate and had to move up a division, who takes it between these three?

 

No, sorry I was replying to a thread I started asking who would have won between Hagler and Conn at 168lbs because he sometimes weighed that much when he fought and I felt Hagler had the reach to help him compete with Conn and stuff, because Hagler took Hearns punches so well I was wondering if Tommy punched harder at light heavy and if Conn could take Tommy`s shots the way Hagler did and someone replied that no middle in history would stand a chance vs Conn so I searched my mind for middles that moved up to super middle and had a light heavyweight reach and all I could come with was Hearns and Nunn (who wan`t that good after he left the Goosen camp and moved up) I feel reach is one of the big problems fighters have when moving up in weight but these too had longer reaches than Conn, ARE you confused? Well so am I, that`s why I posted this so someone can help me figure it out, lol!
