I think it was a win win situation for both parties. Mayweather got his record in a fairly easy fight. At his age he couldn't fight a real boxer without risking ending his career mangled and embarrassed. Mcrgregor was the right balance between a safe bet and the humiliation of fighting a nobody for the sake of an easy win.
Mcgregor on the other hand got his break into boxing. He added a new pool of fans and will make MMA more popular thanks to this.
Not to forget the $$$ they both got out of this show.
Maybe Mayweather could have sealed the fight before. Instead he played safe, he allowed his rookie opponent to tire up and then went for the kill. That was good for the show, it eliminated the risk of finishing out of steam + it reduced the chance of a wounded Mcgregor challenging him again.
Unless Mayweather jumped a few weight divisions then that isn't going to happen. The issue for Mayweather is money, this was a spectacle for what it was and therefore brought in big money. Nobody in or around Welterweight would bring in that sort of money for Mayweather.
