McGregor, Khabib, Rousey, GSP: UFC's 100 greatest stars of all time

Any sort of rankings or tier lists are ever-changing in the world of sports.

The same goes for the UFC with one’s stock being able to plummet and soar in the space of a single bout.

While ranking the 100 greatest fighters to ever take to an Octagon was always going to be a gargantuan task, the folks over at Tapology have done a pretty good job with their ever-evolving rankings.
