It is said by many fans (including myself at times) that Georges St-Pierre has cleaned out the UFC Welterweight division and should move to middleweight to fight Anderson Silva. However, the more I look into this very deep division, the more I see great challenges for the extraordinary champion.
This list contains prospects and contenders that I would like to see take a crack at GSP in the future. Many of them are still raw, but the talent is undeniable and one of these guys could very well dethrone the legendary Rush.
I will not include fighters that have already faced GSP such as Jon Fitch, BJ Penn, Thiago Alves and such, because I'm sure most of us fans prefer to see new challengers with his victories being so dominant.
