I'd be fine watching him comeback. I'm not a McGregor fan nor hater, but he's never been in a boring fight. I'd like to see him fight Nate as Nate's inaugural return to the company to at least have a definitive conclusion to that. Conor, like many others before him, lost the fire once he got the money.
That coupled with him completely changing his stance, footwork, and flow for the boxing fight against Floyd ruined an aspirations if a successful return to championship form, along with the blow and booze.
Use his last three fights as interesting money fights that at least put on a show. He himself knows he'll never sniff another title against today's champions, so we might as well be entertained by his last run.
Chandler and Diaz fights make sense, I just wonder who they'll use for his retirement bout.
