if theyre guilty of nostalgia, youre guilty of revisionism. define a "great well rounded HW" and i will point to Fedor's resume. if you dont have him in the top 5 HW MMA all time then i cant take your opinion seriously. i rank Stipe above Fedor, by the way.
You can dig through his resume but those well rounded ones were either not great HW's, or they never actually used their other skills by then like Arlovski. He never beat a great well rounded HW, he was one himself in a primitive era so he looked better than the rest because of that.
But there's plenty of other reasons why he fails to qualify as well. Like literally taking a year off fighting freakshow Choi and then MW Lindland. Not even defending his Yakuza belt a handful of times etc.
