Yeah, 3 or 4 still doesn't even get him close to P4P #1
Who is the 4th?
Barboza
MJ
Dos Anjos
& actually MJ was ranked 12th when Khabib fought him.

He was a world beater for a while, so I still credit Khabib for the win, but on the real, MJ went downhill big time once USADA came around, so I'm not sure anyone should get big credit for beating him post July 2015.
Pat Healy. Khabib beat him coming off a 7 fight winstreak. Including wins over Jim Miller and Maximo Blanco, big names at the time.
