He wasnt extremely well rounded. He had terribly telegraphed takedowns & very primitive boxing. What made him special was that he had a unique skillset that most of his opponents were unprepared for.
The notion that he "beat his opponents at their own game" is also cringe worthy. He lay & prayed Schilt & grappled quite a bit in the CroCop fight. He also chose to wrestle big nog who had very shoddy wrestling & preferred to box in most of his MMA matches.
I dunno, there's a lot of things he did very well In a boxing sense. His straight right hand was a thing of beauty, some of his hooks were very nice.
boxing isn't just about perfect technique either or looking pretty. It's about being effective. I've boxed for a long time. If were to judge Fedor exclusively on a set mold, then maybe he doesn't look all that Impressive. Many things / styles work In boxing though. Fedor had a smothering style and he was dangerous as fuck. His straight right was very nice, his left hook was decent. He was very wild but that sort of thing works against even technical fighters. In fact, often times technical fighters are the ones who get beaten by a style like that.
Check out his videos sparring against dennis lebedov, former world champion. Fedor can definitely hang and he does a lot of things very well. Albeit mixed with his own aggressiveness / style. At his peak when he was training with ernesto hoost as well, his kicking game was decent.
To say he had primitive boxing Isn't accurate. He could box.
His takedowns were judo / sambo based..not the traditional wrestling style takedowns. He stopped using them after a certain point In his career when he switched camps It seems. Generally those will be more effective In a ring environment.
Obviously his grappling at his peak was very solid as well, although again It seemed he just stopped using It entirely and reverted to a striking mentality at some point of his career. At which point, the best of Fedor had long past.
