The thing is though about this fight is that it's a complete circus act as it is, so a circus ending would not surprise me in the slightest, and no-one can really complain if it does, because how the hell is a man allowed to make his pro boxing debut against arguably the best fighter of the last quarter of a century? The man McGregor is going to "fight" like the boxing version of the 1980's Wimbledon football team (i.e. the crazy gang). Spoil, spoil, spoil, bend the rules as far in his favour as he can (i.e. grabbing, holding etc) and if he gets DQ'd he'll just turn around and say "boxing is for pussies" etc
The thing is that Mayweather is holding all the cards for this fight so he will probably get Joe Cortez out of retirement to referee it so that McGregor won't even be able to look at him in a way that he doesn't like, let alone get in close and rough him up.
