10 Toughest Bastards In UFC History

10. Frankie Edgar

Many wondered whether Frankie Edgar was going to retire following his UFC 240 loss to Max Holloway last month, but the 37-year-old veteran was quick to reiterate how he's still going to compete in UFC going forward. And for the fans of the former UFC Lightweight Champion, that's a great thing.

In a professional career that currently stands at 14 years and counting, Frankie has only ever been knocked out once - at last year's UFC 222 against Brian Ortega - and is largely viewed as being one of the toughest SOBs to ever step inside the octagon.

Throughout that career, Edgar's toughness has been on display for all to see in fights against the likes of Hermes Franca, Sean Sherk, B.J. Penn, Gary Maynard, Jose Aldo, Charles Oliveira, Urijah Faber and even in that most recent battle against Max Holloway.

Frankie Edgar is a machine of conditioning and stamina, and so often he's come back from some brutal shots to again show that toughness that he's so famed for. You also have to remember, so many of Edgar's fights have come at a higher weight-class that he should've realistically been competing at.
