Have you not seen this in every other thread about Aldo and Conor? His coaches turned it down for him because the circumstances were ridiculous. He was still holding out hope of getting a legit rematch, so it would have been stupid to blow his chance for a rematch on 10 days notice even at 145, let alone at a higher weight class that Conor just had a camp for, fresh off medical suspension, with no belt on the line.
Surely you know that "anytime, anywhere" is an expression to say he really wants the rematch, not an invitation for "ok, here's the fight under the worst possible circumstances".
