You are absolutely right about repercussions, on the prelims there were a guy called Bush, his dad was a MMA amateur fighter, for the first time we have a second generation of MMA fighter, that's 40 years of fighting and as u said not enough data for now, especially UFC and other MMA advocates have been telling is for a while that boxing is 100 times more dangerous for the brain, it's very hard to know the truth unless we have complete transparency. Fighting is also a corrupted world, so we don't really know what's going on, what's rigged, etc... A true nightmare in term of regulation...
