The biggest challenge for the UFC in the next couple of years may be finding legitimate challenges for welterweight champion Georges St. Pierre.
If he beats Thiago Alves this summer, St. Pierre will have defeated almost every real challenger the UFC could give him at 170 pounds: Jon Fitch, Josh Koscheck, Matt Serra, Matt Hughes and even B.J. Penn have been defeated by GSP. I suppose it's possible that the UFC could sign Jake Shields, or throw Mike Swick or Carlos Condit at St. Pierre, but when you look at the list of the top 10 welterweights in the UFC, you see that if St. Pierre beats Alves, he'll have already beaten the best challengers the UFC could give him.
The full list of the top 10 welterweights in MMA is below.
