[JustBleed69]

Since Floyd only wants to do boxing, let's close eyes and imagine who of the options below would fuck him up the worst?

Options:
- Conor McGregor
- Khabib Nurmagomedov
- Tony Ferguson

Khabib subs him in under a minute. Tony and Conor all depends on how they went about fighting him.
