And Nothing was the Same
Before his fight with Israel Adesanya at UFC 248, Yoel Romero remarked that fighters were never the same after fighting him. Vague? Kind of. True? Maybe. Yoel followed up with evidence stating that fighters usually have to take a year off after one of his bouts.
But is that really the best measurement of impact? Champions such as Stipe Miocic and Khabib Nurmagomedov have taken extended breaks for a variety of reasons and returned at peak levels. The breaks could have been due to needed recovery, but the "never the same"
expression doesn't really apply here. So who, of all of the UFC fighters, do opponents struggle getting back and staying in the win column after taking a loss?
The chart below ranks UFC fighters by post-fight win percentage. So for example take Mike Swick whose opponents have gone on to fight a total of 43 fights (No Contests are removed from the data) after their loss to him. In those 43 fights, they are a combined 12-31 or a win percentage of 27.9%. The view allows users to set a threshold for the minimum and maximum post fights after loss. This is due to the fact that if a fighter wins and his opponent goes on to be 0-1 before being cut by the UFC, his post-fight win percentage is 0 but that really isn't all too telling.
*UFC fights only, No Contests removed
For me, George St-Pierre stands out the most here. There are only 4 fighters in UFC history with as big/bigger fight trees than him and his post-fight win percentage is significantly lower. Much of that number has to do with BJ Penn, who went 6-11 after their first fight and 3-9 after their second. That being said, fighters such as Josh Koscheck, Carlos Condit, and Johny Hendricks (who arguably won his bout) all struggled to stay in the win column after their fight with GSP.
