Is saying McGregor has a chance the same as saying Floyd has a chance in the octagon?

I know as flights come closer peoples opinions change

But really, McGregor has no chance

Is it not the equivalent of Floyd fighting him in the octagon, Floyd would have no chance!!

Or am I seeing it wrong?

A 28 year old mayweather vs a smaller, formerly retired 40 year old mma fighter with a tendency for standup doesnt seem too bad.

Boxing has fewer ways to end a fight so it stands to reason that a novice boxer would last longer in the ring than a novice mixed martial artist would last in the octagon

On the other hand, I guess it is true that there is one aspect of MMA in which Mayweather would have an advantage over McGregor, i.e. punching, whereas there is no aspect of boxing in which McGregor has the advantage over Floyd
