Why can't Floyd vs GGG happen?

You probably shouldn't expect that of prize fighters because it isn't fair. Weight classes exit for a reason.

And I agree with you 110 percent and beyond with you on the need for weight classes and the reason for their existence. But, noone (except Bernard Hopkins) has asked Floyd to fight where he hasn't competed professionally before. If anything, it is the other way around on this subject; fans are wanting Gennady to fight where he has never competed professionally. If the stated concern were for Gennady's safety I could understand that a little more as we don't know how his body would react to the drop in weight. If when Sergio challenged Floyd at 150 the stated concern was for Sergio dropping 10 lbs at his age, I would be more understanding as he hasn't been that low for a very long time (I think Sergio began as a welterweight). But, it hasn't been, on both occasions, in which fairness was more on the side of Floyd than either Sergio or Gennady.
Floyd is the most technically sound amd proficient fighter that we have seen and will probably see for a looong time. This can't be logically be debated, I think. But, my argument, here, at this moment, is only that he has been very carefully selective of his opposition at certain points in his career to protect his record. My argument, here, is nothing more or less than that.

No man. These fighters already risk their lives for their sport. By that reasoning RJJ was obligated to fight Lewis. He wasn't. He was brave enough to make a claim at HW, that doesn't mean he owes the division his career. Floyd is not a big Welterweight, he certainly doesn't need to fight MWs to prove himself. Not anymore than Triple G needs to fight at LHW, or Ward needs to fight at HW. Weight classes exist for a reason.
Edit: By your standards I want to see those other fighters ACTUALLY compete in those situations. Triple G's team has bragged about how they'll fight anybody up to 168 but run from Ward. Pa has never actually fought a 154 fighter but fought a beaten Margarito at 151 and fought Cotto at 145. I'm so sick of Floyd being held to a different standard because you haters want him to lose. I'm sorry he is legit better than all of your favorite fighters. Get over it.

Big difference. Rjj is a paper champ at hw no doubt, still a major accomplishment. Floyd 2x, lineal, unified, reigning champ at sww who's already proved reluctant to give up the belt he's too small to wear

the reason people keep throwing GGG's name around is because floyd won't fight the best in/around his own division. ... I mean he won't fight pac ... won't fight bradley etc. So people start saying ok then you won't fight who you should be fighting so how about GGG?

if he was was lining up pac next, bradley after that followed by danny garcia etc etc I for one would be delighted and imo nobody would bother mentioning GGG. But when he refuses to go up AND refuses to fight the best in or around his weight people rightly get pissed at him ... I mean kahn or maidana?? sheesh he's supposed to be p4p no 1.

Exactly. He makes excuses to not fight people around his own weight as well, and when he does fight its once a year at most mostly and more like once every 18months in reality. And to avoid people he says he is with TR, or he is hbo or whatever.

Then they twist that people wanting Floyd to fight GGG as GGG called him out, as Floyd being held to higher standards? I mean, Floyd fans try winding people up.

We want Floyd to fight GGG, as he is basically avoiding everyone else in his divisions or waiting ridiculously long to make fights happen.

Floyd is too small for GGG.
