Great sparring. This shows that Fedor had an understanding of boxing well beyond that of any other MMA fighter. I think he would have been a great boxer if he picked up that sport in young age, we now know that he has an iron chin and can't be knocked out and he had a lot of natural power. If a bum like Wilder who started at 22 can make it Fedor would definitely hold a world title at HW at some point.
