Carl Froch wants to fight GGG?

He shouldn't avoid the fight, even if there is a big chance of him losing(which there definitely isn't), he should still fight. Like you said yourself, everyone had Bute to beat Froch, but he still fought him. It's boxing, if you don't want to compete with the best, there's no point in lacing up the gloves in the first place.

GGG has a resume that is in par with Guillermo Rigondeaux and Andre Ward, only thing less he has is as gold medal and that is all that he lacks compared to the other 2. We all know what happened when Guillermo met Nonito and Guillermo only had a handful of matches. GGG has knocked out opponents in amateurs with pillow gloves who are now fighting at Carl Froch's division including Bute. Carl Froch has to avoid GGG or he might get his fight KO loss. That being said I am eager to see what happens when Stevens land on GGG, does GGG's chin hold up, that is a big question still to be answered in his proff career. When you have over 400 amateur fights and 5 loses, you have fought everybody and every style. His opponents in amateur look like a proff list and he knocked most of them out. There are talks Vasyl Lomachenko is going to get his title shot at his 2nd pro fight because his amateur career too is in par with the above mentioned.

Every great fighter needs that fight to prove they are the best, the fight were they are the underdog and need to win against the odds to fulfill there potential.

Ali was huge underdog vs Liston

Hatton was gonna be a two round job for Tszyu

Mayweather was gonna be to small and defensive for Oscar

GGG hasn't fought at the level of froch

See, most great fighters have the one fight, this fight is GGGs chance too prove he is great. He shouldn't duck it or he may never get the opportunity again.
