Connor is a fantastic fighter no doubt about it. The UFC and that new ownership should be fucking giddy, because without him things would be pretty bleak. The heavyweight division, which previously oiled the gears of the organization, was their biggest attraction, with guys like Lesnar, Valasquez, Dos Santos, etc 5-6 or so years ago along with GSP. But injuries and championship carousel started to tarnish the brand. McCregor slowly starts to earn a name and they rightly played him into a position where he could have a platform to talk. He backed it up, and to his credit he is in the position to make more money than any MMA fighter in history by far.
I think its good for the sport though because if another guy can defeat him soundly and has at least some star power they can try and ride that train as long as they can, while still featuring McGregor as a redemption story if he rebounds. He needs to fight Aldo again IMO.
