McGregor in midst of $100M deal with UFC?

Conor McGregor told ESPN’s Kenny Mayne, in the network’s trademark “Sunday Conversation” that he is in the midst of a $100 million deal with the UFC.  In the interview, he opened up about the “retirement” tweet, the UFC and Floyd Mayweather.

Whether or not you believe this to be true, the deal is likely the biggest fight contract for a UFC fighter in the company’s history.
Assuming what McGregor is saying is true, the deal is likely for 8 fights which would amount to approximately $12.5 million per fight not including any PPV upside or other performance-type bonuses.
The interview includes talking about the “proposed” fight between Floyd Mayweather, Jr. and the Irish MMA fighter. The latest in that saga is Mayweather offering $50M to McGregor. In his ESPN interview, McGregor proclaimed that Mayweather needs him, not the other way around.
Payout Perspective:
I would suppose that McGregor and the UFC would be working on a new contract (or revising the old one) which would mean more fights and more money. I also think that the contract would be much more in-depth and detailed than your standard boilerplate contract with the UFC. Namely, it would detail the terms of his promotional schedule.
The subtle thing here is that McGregor is giving ESPN’s Kenny Mayne this exclusive interview and not Fox or FS1 doing this. Obviously, it would be more advantageous for ratings if FS1 were to do this interview rather than ESPN. But, as we’ve seen, when big news occurs for the UFC, ESPN is the first to report.
