I think it's completely unlogical to believe he has any hope of a chance, all this talk of "Conor needs to do this early" is completely ridiculous, it isn't going to be a "Conor needs to.." it's going to be, "oh shit, can he make it out of this first round"
I don't think Floyd will knock him out in round one, but it's possible.
Conor doesn't move nearly as fast as people have been making him out to be some lightning quick striker.
He has excellent reflexive timing, vision, and a snappy quick straight left, he's one the best to use the slip straight hand in MMA.
It's just that he will appear many magnitudes slower across from Floyd, just watch.
