It would make a pretty big bucket of money with zero consequence to Conor's value as an MMA chip, so it does make financial sense.
If you want to milk Conor's value to the absolute max, with max returns, you do the following:
- Paulie boxing (still 2 division champion regardless of outcome, huge upside if he wins)
- Fight GSP @ 170 (still 2 division champion regardless of outcome, huge upside if he wins)
- Hope a new 165 weight class materializes and fight the Nate Diaz trilogy for the new 165 lbs title (still 2 division champion regardless of outcome)
- Look for a Nick Diaz fight (still 2 division champion regardless of outcome)
- Nurmagomedov @ 165 for title in Russia if he's still at the top (still 2 division champion regardless of outcome, huge upside if he wins)
- Consider whoever is holding the 155 strap if they are massive draw, or keep cherry picking superfights
I feel like he could rattle off all those fights for blockbuster paydays regardless of whether he wins/loses them - especially the first 4 fights I listed.
On the other hand, if he decides to go fight Tony (proven not to be much of a draw), and loses handily, all of the above fades big time in terms of earning potential.
