How would Saunders do at 175?

[boliodogs]

I don't think he would do well at all. All the champs would knock him out. He doesn't look lean at 160. I think he would be a fat boxer at 175. The extra weight wouldn't increase his punching power but it would decrease his speed.

He'll ko Stevenson

[killakali]

Could he beat any current champions there?

Could Errol Spence, Keef Thurman or Terence Crawford beat GGG?

Could he beat any current champions there?

No

175 is a strong division, unlike 147

[Dodger07]

He would get destroyed

[Madison Boxing]

no, the fighters are both bigger and better than him. and for the record i think spence could beat saunders at 160. hes terribly overrated, john ryder, a very green eubank jr and akavov (is that what hes called?) gave him fits.

I did notice there is a significant change in size from MW to SMW. Like fighting in SMW is the same as fighting at LHW because SMW are basically the same size are LHW, just as SWW are the same size as MW.

Absolutely. Historically it's uncommon for Middleweights to move up to LH. For Middleweight title holders its almost never. There are a few exceptions but few and far between. It's like you say there is a big jump in the size between the two divisions. That's one reason boxing added the SM class.
