GSP is just too great of an athlete for Hughes. Hughes' only advantage was his strength, but GSP nullified that by keeping it on the feet. It really seems that the Miletich camp isn't evolving at the same rate as the other elitle fighters in MMA.
That being said, BJ Penn is really the only theat to beat GSP at ths time. IF he comes in shape, Penn should be able to finish GSP this time (their first round was pure domination by Penn).
