George Groves - A shot fighter at 27?

I have written many times that I feel sometimes a loss can change a fighter massively.
I picked Groves to win the first Froch fight, but said before the 2nd that I wasnt as sure although still slightly favouring him, how he would be after a loss as contraversial as it was.
I now thin k the decisive loss has had a massive effect.
Just look at some top fighters and P4P fighters in how they look after a loss
