Connor has a big advantage in this fight, Porier will likely get KO/TKO under 2.5 rounds. The bigger fight would be Khabib coming out, Connor doesn't want that - he would get destroyed again. There is a pretty clear #1 and #2, and then everyone else.
Khabib Won't get it thru Conor this time . McGregor is too Thirsty now and will not allow anyone to stand His way.
Though of Course Things happen sometimes but i doubt that by Any chance Conor will Lower His Defense and Offence for any fight this soon.
