Froch by a distance for me. Alone his win over Pascal trumpets anything Hatton and Khan did/ have done. I also think its fair to say Froch has improved significantly since then.
It's become fashonable to downgrade Hatton following the Pacquaio debacle (and to a lesser extent the Mayweather loss). In his prime though, he was a very good fighter with one exceptional win on his record, and some solid wins like Castillo, Malignaggi ans Urango. Froch deserves all the credit for the quality of his opposition, but in another era he would just be a hard-as-nails take-on-all-comers top 10 guy. At no point has be been the man at 168, whereas Hatton was a deserving champion at 140 for a number of years. Why is Khan even in the debate?
Why is Froch even in the debate? It's laughable that he's even got 20 votes. Ricky surpasses him on legacy by a country mile, especially if we're including losses. Remember, Froch didn't beat Ward or Kessler. With Khan, he's also fought the best in his weight division, bar Bradley, who refused to fight him. If Khan should not be included in this, then Froch shouldn't either.
Hatton was awesom, yeah. All he needed was more ring intelligence and he'd be unstoppable. Failing that, he needed more ducking ability, and he'd be retiring about now as Britains few undefeated champs of recent times along with Joe Calzaghe. wellTerryMarsh too but he got ill it dont count.
