Saw Kerr fight at a Cage Rage show sometime ago, also saw Dan Severn. Both fighters lost and were very **** to be honest and it is very disheartening seeing them like that. As for the documentary, very, very good.
I saw the doc as well, I remember all the needles he had all over his house, every drawer seemed to have a pile of them. I wouldn't be surprised if he suddenly died form the drug use or suicide some day. It's hard to go from one of the best in the world to a guy who looks nothing like he did before and fights in regional shows.
