I dunno if it's the longest interview but.... but it touched upon some controversial themes, so kudos to the interviewer.
The bits about the upcoming fight were boring.... He likes Jackson as a person -
There was a bit about testing in Bellator and how some people claim that there's very little if any testing done in Bellator - he said he's always being tested before and after the fight by the commission, though no out of fight testing has been done in Russia.
There was a bit about the Russian media - he said he had a few interviews with Russian media in the past and his words were changed, taken out of context, etc - he prefers not to give interviews to the Russian media for that reason.
Then they talked about his brother and this bit I found particularly interesting because Fedor hasn't been very open to discussions about Alexander
Fedor said he saw Alexander's most recent fight, but it wasn't sport - it was more like anti-sport. He said he'd compare it to circus, but such comparison would have been offensive to the circus (alas, hasn't he been in a few circus fights himself?).
All in all.... while there is word that his brother is going straight, Fedor doesn't buy it. To him, Alexander is dead (his words). For Fedor to change his mind, he said his brother should first make amends with all of the people he's raped, stole money from, lied to, etc. Only then is he going to recognize that Alexander is starting to straighten out his life and his lifestyle.
