If the Conor/Alvarez fight was yesterday then I would definitely say Max is in trouble, given the way he got hit by Dustin in the opening rounds.
But that was years ago.
Conor looked slower against Khabib, and I would venture a guess that he's putting in a fraction of the work he used to. If anything Conor looks bigger and heavier than he used to, which is going to slow him down and gas him out even worse.
Conor still has KO power, so I'd give him a shot, but Max has a god-tier chin and cardio for days. I can see this fight going a lot like McGregor-Diaz 2 which was very close, but given McGregor's slide I think Max wins that late.
