The biggest fight for Kambosos Down Under would be Loma, who has more international appeal than the other guys.
It depends what metric we're using... Most significant for resume/legacy is clearly Loma. Biggest payday quite probably Tank.
There's no reason whatsoever to think otherwise. The question is whether GK is more interested in legacy or making money out of his belt. There are still plenty of observers asking questions about just how good George is - beat Loma and a lot of those questioners quieten down, his profile goes up amongst fans and he's remembered... OTOH, beat Tank and the casuals will know who he is, and his ability to sell PPV afterwards will increase plenty. All this is academic anyway, no way Tank gets in that ring with GK.
Why is Floyd to blame? Tank is going to fight who he wants to fight at the end of the day. The mega fights are coming in 2022.
Depends if he's more interested in inching forward and protecting his 0 or taking risks that might push him onwards. Plenty to choose from either way. But this really is the important question - does he care more about being truly great or about keeping the KO% high and pulling in lots of PPV$?
Bro Loma has been beat twice…he has no belts and the shine isn’t what it used to be. What makes it such a great legacy fight?
He's still the most proven at the weight - two losses don't change that, this obsession with zeros needs to stop. If you're looking for legacy at 135 and you're active at the same time as Loma, there's something missing from your resume if you don't fight him - and if you sleep on taking that fight, it's always going to be held against you. It's also one of easier of the big fights to get made because Loma isn't going to duck (or constructively duck by pricing himself out of it). It's still the fight to take for legacy IMHO - certainly above taking fights against popular fighters who are potential hypejobs (and will be remembered that way if you beat them).
