Who has been KO/TKO'ed the most in the UFC... so far I've only found Frank Mir to have more KO/TKO losses than Overeem in the UFC altho it's over 14 years compared to Overeem's 5 years
Rashad Evans only has 3; Lyoto Machida, Glover Teixeira, Anthony Smith. All other losses were decisions (not that bad considering people are calling him to retire!!)
Bisping only has 3; Dan Hendo, Vitor Belfort, Kevin Gastelum
Ryan Bader had 3; Lyoto Machida, Glover Teixeira, Anthony Johnson
Keith Jardine had 4; Houston Alexander, Wand Silva, Thiago Silva, Ryan Bader
Mark Hunt has 4; JDS, Werdum, Stipe Miocic, Overeem
BJ Penn has 4; Hughes, GSP, Frankie Edgar, Yair Rodriguez
Chuck Liddell has 5; Randy Couture, Rampage Jackson, Rashad Evans, Shogun, Rich Franklin (I'm not counting the Rampage KO in Pride)
Overeem has 6 IN THE UFC over 5 years period; Bigfooot, Travis Browne, Ben Rothwell, Stipe Miocic, Francis Ngannou and Curtis Blaydes
Frank Mir has 8 over 14 years period; Ian Freeman, Marcio Cruz, Brandon Vera, Brock Lesnar, Shane Carwin, JDS, Josh Barnett, Mark Hunt
