There is no "potential fight", potential fights have an actual chance of happening, this thing does not, period.
We can discuss the matchup i guess, thing is, Paul is considerably bigger, he fights at 190lbs iirc, and tonight was 200lbs, Conor fights or used to fight at 155lbs, sure he got bloated recently but still, that doesnt turn him into a 190lbs boxer, he would still be outsized if he ever tries going to WW in MMA.
I would probably pick Jake Paul on size and some athleticism alone, if they were both around the same size it would be more interesting, Conor is clearly past his best days, that would be an interesting pick, in their current form? Jake Paul all day.
Fight isnt happening simply because Conor is tied with the UFC with whatever is left of his fighting career, he wont fight anywhere else, ever, and if he manages to leave the UFC then he wouldnt go after a beating by Jake Paul, Floyd would be WAY too old to go that route, Nate Diaz? Another old man too, but that could actually happen in MMA, no need to go into boxing for that.
