Huge Conor fan here, but I'll keep it real.
I think as silly as the Till talk is because he really is a (MW) gorilla, Conor is also a gorilla...with the same reach as Till, might even have bigger lunchboxes. He'd do better than most people think, but I wouldn't bet on anyone in that fight.
I think Ortega gives Conor a good fight standing. Solid chin to hang and weather the initial storm ala Nate Diaz.
For the record I don't think anyone, not Nate, not Till, not Mayweather would beat Conor without a good chin to hold them up. Because Conor beats everyone to the punch in the early rounds. Yes even a skilled undefeated pro boxer notorious for not getting hit. Oh, but he is a senior citizen now, or no wait he "gave away" rounds because he supposedly likes to get hit and had the foresight that he could take the punches (make up your minds haters; is he a masterful strategist that there's no way anyone could beat or is he old and washed up!) I read somewhere he landed significantly more than Manny did. That's just because he's slower and nicer in his old age though, right?
