For my money, GSP and Anderson Silva are the two fighters that represented their generation. Trail blazers in the UFC in showing that these Superstars can be made that are able to defend the title, time after time. They say a fighter is best when they have the correct combination of mind, skill, and athleticism. IE: As fighters get older and become less athletic, their actual skill level may rise due to the additional time put in at the gym. The best fighters are the ones who were able to capture all 3 factors at one paticular moment in time. So my question is if you were able to clone GSP at all his stages of his career, and made the clones fight, which one would be the best. My personal feeling is that the best Welterweight we ever saw on the planet was GSP vs Koscheck 2. The striking and wrestling were out of this world, and he was able to defeat one of the top contenders in UFC history. Are there any other opinions on when he was at his absolute best?
