Froch cant be considered overrated, more like underappreciated. After the guts that this man showed against Pascal and Taylor, you must hate him not to like him.
I did not intend to say that the 168lb class sucked, but rather that it is a bit "watered down". There are no real standout champions or dominant ones that I can see. There are some that are better than others, but you can make an argument for just about anyone in the top 10 or so. I mean in a lot of cases thats good because its very competitive. It also can be viewed as missing something since it does not have any dominant champions...I guess its in the eye of the beholder. Personally, I love boxing so any division (130lb and above) is fine with me. I really wish Lacy would not have gotten the confidence beaten out of him by Calzaghe. He was interesting in the mix before the beating and the injury.
I don't think Froch is overrated at all, he beat a current light heavyweight champion in Pascal and also a former undisputed middleweight champion in Taylor, so he has clearly beaten better fighters than Bute. I wouldn't see Bute is overrated either, i haven't really heard anyone overrate him. I'd say hes a B class fighter as of now.
