[Hanna Sniper]

I wouldn't say GSP's skills were diminishing, although he was getting older and you do slow down a bit I really didn't see his skills diminishing to the point he was no longer still the best fighter in the game

I think he suffered from being obsessed and too focused, that diminished his end result but I have zero question his skills were all there. The fear of loosing took away his killer instinct. Without that killing instinct and the knowledge that winning that title means more to your opponent then it does to you will eventually result in you taking one hell of a beating... he knew this and props for seeing it
