Compared to boxing, having the GOAT of all time IMHO (Jones) move up in weight to fight a killer like Francis for $10-15 million is literal pennies to the UFC.
If you think Jones is scared of Francis, you're out to fucking lunch
Jones hasn't ducked anyone in MMA, he's walked through literally everyone. The guy is at the last legs of his career here, I don't blame him for wanting a big payday.
The reality is if Jones wins the HW belt, he's not going to be sticking around and defending the damn thing.
