If he is serious (about this stupid idea of coming back) then he needs to fight someone who is going to take him half a dozen non threatening rounds and then falls over, so Hatton gets rid of some ring rust. On paper Ranee Ganoy fits the bill: http://boxrec.com/list_bouts.php?human_id=205664&cat=boxer
Hatton needs to fight someone he can KO. He would be N'dou easily but not by KO the dude went 12 rounds with Canelo at 150pounds he has never been stopped. I reckon he should fight Kermit Cintron.
I don't think he does need someone he can KO I think he needs someone who will take him 10/12 rounds to see exactly what Hatton has left in the tank N'dou fits that bill
Well that would make it more likely, imo. Anyway was just a suggestion. I think he would be a decent comeback opponent.
He also doesn't want to fight someone who could put him asleep. Cintron is incredibly erratic, but if he caught Hatton, it would be comeback over very quickly. Malignaggi down the line I think, but for immediate opponent who knows.
