The only fighters on that list that haven't been finished with strikes are Lineker, and Condit. Most of those fighters have been ko'd more than once lol. Condit's chins rank right up there with Frankie's as all time greats and lineker hasn't been through enough wars yet to prove any sort of longevity.
You can't even name fighters close to his weight without naming fighters that have been finished multiple times with strikes. Frankie has been outsized, fighting much better competition, with more time in the cage than all those guys. His chin belongs near the top of that list.
And yes, I said in his weight classes (shouldn't have to repeat that over and over and over) but you jumped on the one time I didn't clarify and still came up with a weak ass argument. You just named your top chins ever these guys have been finished with strikes:
Leben 4 times
Hunt 4 times
Penn 4 times
JDS 3 times
RDA 3 times
Hendo 3 times
Nelson 2 times
Barao 2 times
Diaz bros, DC, and Sanchez are tied with Frankie at once.
All these guys with supposedly iron chins weren't able to absorb as much damage as Edgar without going down. Face it, Frankie's chin is legendary and you are a hindsight 20/20 revisionist history know it all hipster.
Why do Hunt, Leben, and Hendo get the benefit of the doubt after getting flatlined over and over, but Frankie doesn't after getting finished once.
Frankie has the all time record for time in the cage without being finished. He is literally ranked number 1 for longest time in the premier organization without getting ko'd. If his chin isn't an all time great, how did he outlast everyone else? Face it, no matter how bad you want to be right, your not and the more you argue the more ignorant you prove yourself to be.
