As he should refuse, IMHO, and it wouldn't be Jones who is responsible...it would be Stipe. The onus is on the contracted fighters to both make the walk, not on the guy who did not drop out to suddenly agree to a new fight on short notice.
Jones is also the one with far more to lose, while Pav would have everything to gain. IMHO, it is unreasonable to expect that Jones accepts the risks to his champ status, earning potential, and legacy without the desired time to prepare.
I would have agreed with everything you said here 5 or 10 years ago, regardless of any mocking I may have done to Jones for blatantly
ducking declining to fight Chael Sonnen (of all people) on short notice.
I have a long history of
supporting fighters decisions on things like this. Shit, I felt like I was the only fan on sherdog who thought Zabit shouldn't feel obligated to change a 3 rounder to a 5 rounder at the last minute, just because the prior main event got canceled.
But the conversation has changed. Dana now pays backup fighters months in advance. Every party understands this. Jones understands this. Fans know this. There is no last minute surprise anymore. And Dana did all this to avoid exactly this scenario.
I said earlier - and I stand by it - that Jones probably
could decline Pav on short notice and probably
still get more fights later. He just simply has that much negotiation power, that much juice.
But regardless of all your justification above, most fans wouldn't be able to justify it. It would be that bad a look. So bad a look that
even Jon Jones wouldn't do it, IMO. Then again, he's surprised us before lol
EDIT: but, hopefully this is all useless conjecture. Cheers.
