The only person who said M1 wanted to fully co-promote was Dana. When M1 we're interviewed about it, they said they wanted to co-promote in their HOME REGIONS ONLY = a totally reasonable request, and the version of events I choose to believe.
M1 are dodgy. M1 have Fedor hostage. M1 are the mafia. All a load of Dana White bullshit pushed by the western media, that we all swallow and ask for seconds.
It's hard to say what level of co-promotion they wanted, but from Vadim's own words, it didn't seem to be just in eastern Europe:
“We’re only going to work under co-promotion conditions,” Finkelchtein stated. “Our offer was very simple, we offered to have a co-promotion — two fights, three fights, doesn’t matter. And we were ready to invest in that show together and to get the profit together. But the UFC made a different offer that was a very good offer. But the same offer (they made), we can actually make to their champion. We can also offer millions to them and one, two, three, four fights to them.”
That's from a 2009 press conference.
To me, it sounds like a full co-promotion, but of course the details are sparse.
Dana's always been full of shit. He claimed that it wasn't just about bringing in Fedor but also bringing in a bunch of other Russians. I would be really curious to see all of the Russians the UFC passed on and if they are the guys that are killing it in Bellator right now (Alexander Volkov (HW), Vitaly Minakov, Mikhail Zayats, Andrey Koreshkov, Alexander Sarnavskiy, Shahbulat Shamhalaev, Frodo Khasbulaev).
I only really remember them talking about signing other Red Devil fighters in 2007. The two names that didn't get confirmed, but were kind of floated out there, were Amar Suloev and Roman Zentsov.
Obviously, if they had had a better relationship, they could have gotten more Red Devil fighters in the future. But I don't think most of those guys you listed are Red Devil fighters. Volkov is I think, maybe Zayats.
