GGG appears to be a once in a generation type of fighter. He has welcomed any and all to step up, but few have had the stones to 1) do so, and 2) go out on their shields
He appears to be no such thing, let him win a tough competition before adorning him as such. Chances are he ends his career in 4-6 years as "Yet another talented European fighter who wasn't an ATG"
Murray wasn't in the top 10 when he faced GGG? Macklin? What rank was Rubio (who was holding a title at the time) when he faced GGG?
middleweight is a helluva lot more interesting than super mw. besides those mentioned, Murata, Khytrov & Tony Harrison are all undefeated, have power and rising up the ranks. if Lemieux beats N'dam that'll be a huge fight in Montreal & facing Eubank Jr would be big in England.
There are a few fighters left for him: Lee Quillin Cotto Alvarez Lemieux People will find faults in all of them and call them cherrypicks, but fact is, Golovkin is too good, he made MW's top fighters look like bums but people aren't aware he fought a multitude of top 10 (and top 5) middleweights.
I agree 160 is pathetic because it's "champion" is a coward who absolutely refuses to fight his mandatory.
