"It's a great fight. It's Pacquiao-Mayweather."

GSP vs. Silva involves that rare moment in time when the most sporting significant bout intersects directly with the territory of being the most fan-demanded, most financially lucrative fight currently available. In a world where contractual limitations don't exist, there are other fights that could be bigger. Fedor vs. Lesnar, perhaps at the time it was most feverishly demanded, could've been bigger. But that fight has lost its luster and is anyway unattainable. If we are talking about two fighters who exist in the same contractual universe whose pairing meets the aforementioned criteria, GSP vs. Silva stands alone.

...GSP vs. Silva is more Pacquiao vs. Mayweather's little brother than peer. It won't garner the world wide attention or breach the North American sporting consciousness in a way boxing's mega fight would. But putting on GSP vs. Silva would be hugely beneficial in raising the awareness of what MMA's finest fights can look and feel like, particularly in the absence of Pacquiao vs. Mayweather.
