Which of these 168 fighters can be beaten by GGG?

All. Ramirez is the most complete fighter of the flawed bunch, but GGG would walk through his punches and work that body. 168 simply is no better than 160, and if Canelo actually committed to 160 then MW would actually be the better division.

all of them but i don't think it's worth moving up until degale and jack fight each other (if haymon wouldn't block the winner from facing GGG) or zurdo gets a couple more good wins the dirrells, bute and sturm are no better than GGG's options at MW. in fact MW has a much stronger crop of up-n-comers right now

none GGG would actually have to move to 168 to beat anybody there and he is afraid to do that. He likes to TALK about beating 168 pound fighters though. Hell I bet hes even beaten some "IN SPARRING" already, just check with his fans, they maintain a list of everyone GGG's beaten "IN SPARRING"

I think GGG beats them all.

Sturm and Anthony Dirrell. That's it. At the amateurs, he already beat A. Dirrell and he KOd my boy Bute cold with his headgear on...

I find all of these fights to be interesting,just because of size and weight difference. How will supermiddeweights be able to take golovkins power,and vice versa.

I don't think him changing his style benefits him moving up. He's not the fastest, so trying to be clever trying to box on the outside vs longer, taller, heavier opponents isn't the best move, instead he should do what he's always done and try to impose himself and his power on these guys. Might take a couple more shots but, even if he has to come in light to keep his sharpness, he should go for it, being bloated isn't the answer. His punches, especially to the body will still have these guys crumbling.
