its just hype.. we dont know 100% if GGG is the goods either but if you just look at the ease in which he has put away some very tough fighters i am 95% brought in to the hype stevens would get viciously hurt
If GGG is to fight twice more this year, this would be a good fight for one of those bouts as Stevens is coming off a good win where he showed one punch KO power. Enough to make a fight vs GGG interesting at a time when most MW's are avoiding him.
