Well, if the farcical match-up of Renan Barao vs. Jon Jones was booked tomorrow, yes.
You people all severely overestimate a wrestler's ability to create space for GnP though. Wrestling is not the best base for mma because it has no answer for the guard. What the fuck is he gonna do if I pull on his head and destroy his posture, push my back into the mat?
Just because shitbag judges who don't understand guard have fooled you into thinking "wrestler laying in top half of neutral position = 10-9" does not mean the guard isn't actually effective.
And maybe you don't want to wind up on your back in a street fight, but if you do then it's better to be able to sweep someone standing over you, or tear apart his knees with heel hooks than otherwise.
