I sympathize to the Filipino's camp because like Inoue, he is also a champion and the holder of the WBA and IBF belt, though not a crowd drawer but still he should some ample share of the pie not pay them pennies.
Just forgot the link but i will share once i find it.
And maybe this is the link that you are referring, https://sports.tribune.net.ph/2023/08/02/inoue-unification-fight-talks-collapsing/
They need to negotiate and not just to accept that low baller, even Inoue will bring the most of the sale but the point that
Tapales is also a Champion/title holder should be consider in terms of the offers.
And if Tapales decides that the offer is not good enough, he will likely abandon plans of unifying all four championships in favor of making a defense against former world champion Tomoki Kameda.
I like Tapales and his team standing their grounds here, he has the two other belts as you have said, if there is any here, it could be 50/50 split as both has the belts. But let's see if Inoue's camp will soon realized that low balling the Filipino will not help Inoue unify all the belts at 122 lbs.
Maybe if Inoue is after in unifying all the belts, they will renegotiate and bring other options for
Tapales to agree, but if not, chances that Inoue will move to another division or will try to find
another challenger to defend his belt.
