Kavanagh says he was initially skeptical about McGregor taking on Mayweather.
When I first sat with him and he started explaining the Mayweather fight, it made no sense to me. By the end of the half-hour conversation, he had me shadowboxing him in the room, watching boxing videos…[After Conor and the UFC come to their agreement] it became a lot more real to me. I was enjoying the buildup, the talk, the idea of it. But it wasn’t until Conor messaged me and said, ‘It’s done, I’ve signed,’ that I was like, ‘Oh, OK. We actually are boxing.’…There could still be negotiations going on four weeks out, but the big mistake would be to mentally put off the heavy training until every detail is agreed upon. We are training now. We’re ready for that date in the fall, whenever that might be. We’ll let the lawyers and suits deal with the nuances of who gets this and who gets that. Conor is a fighter. I am his coach. We’ll focus on the contest at hand.
