Both fighters were dropped by lesser fighters with fewer KO's than GGG, I think if GGG dropped either of them he finishes them both, he wouldn't take his foot of the gas like he did with Murray and Monroe. Be it on cuts, be it on accumulation, be it on straight up KO, he stops them both late. Sorry for the wait I had to go somewhere and left browser window open.
GGG by UD is also entirely possible.:deal Although that wouldn't look as good as "GGG Brutally KO's all 4 of them":yep
