Yeah it really is hard to pick. If I was forced to pick one, it'd be Nogueira. His dominate run as champion and P4P best in PRIDE was when I started re-watching the sport religiously. Hadn't watched it regularly since the really early days. When I re-caught up with the sport, Nogueira was fighting Gary Goodridge. I followed his whole run from there, and man he's just an inspirational figure. One of the greatest of all time. Gotta respect what he's done. I badly wanted him to get Fedor back, and somewhat expected it to happen because Nogueira made a career out of doing what people thought he couldn't do. Unfortunately, Fedor is just the man right now. Well not unfortunately for most, but for die-hard Nog fans like myself, it's a shame that finally someone came along that he couldn't defy the odds against.
