Either when he lost on points to Dirrell, or lost almost every round to Taylor, or when he did lose every round to Groves.
Doesn't matter, Froch was a very limited crude brawler who's chin and physicality got him to world level. He'll be forgotten pretty soon.
Anyone with eyes knows this, worst punching technique I've seen at world level, one of the worst defences. He ate flush shot after flush shot in almost every big fight. If he didn't have such a good chin he would never have won a title.
What the one he avenge in a rematch and the Ward fight where Ward duck the rematch because he had to come to the UK and be PED tested? :think
Ward won the fight by complete shutout and in doing so showed he was a completely different league to Froch, if Froch wanted the rematch so bad he should have given the CHAMPION the lions share. To say Ward ducked Froch, a fighter who he dominated, is completely laughable.
But nobody pays money to watch Ward people pay money to watch Froch. Simple. And it wasn't about the lions share, it was him saying he could fill Wembley. He can't and he knows it.
