Because the fighters are human. Humans have emotion. Fear is an emotion. It's the same reason that a WR would get alligator arms when they try to catch a pass over the middle of the field. Quillin hears footsteps and knows he's gonna get the dog **** knocked out of him.
Winky out for 3 years, no wins in 6, as pointed out. Guerrero no good wins, ugly loss to Brewer. Did you just see him get dropped and rob a no name out of prison? NJikam no top 10 wins, dropped his interim belt when ordered to fight GGG 9 months prior
the answer is Golovkin. and his not so good resume is to do with everyone ducking the guy. Quillin has a **** resume by choice. big difference. but Golovkin still has the better resume of the two.
Macklin is the best single win here. N'Dam is probably second best between the two and Winky and Guerrero are notable. Brinkley and McEwan, however, Quillin's two best wins beyond those three with a significant drop off of opposition after them are pretty weak compared to Golovkin's top of the resume. But Golovkin does have a pretty ace list of slightly lesser than that caliber opposition to the point where quantity may overpass that quality. I don't read into it any more than just the surface, but look at their common opponent of Rosado. In the end, anybody who says they aren't somewhat close to each other are the only ones wrong here.
Sure Golovkin's resume isn't great because the top fighters are ducking him, but Golovkin and his management deserve some of the blame as well. They have, on numerous occasions claimed that they would fight anyone from 154 to 168. It's better that he move up or down in weight to fight good competition than to fight someone like Adama.
Nonito Smoak pretty much said it all. Resume wise it's quite even, at a push, maybe an edge to GGG. Taking their performances and how they handled their competition into equation though, it really isn't anywhere close. Golovkin just looks the better fighter with maybe the potential to be something great, which is entirely where his hype is coming from, not his paper thin resume.
