Was last night's fight the proof that GSP is the true P4P king?

If you compared that fight to the aldo/hominick beforehand, that fight showed how slow and too cautious both shields and gsp were, shields didnt try to take him down to the ground, gsp didnt land combination except for the continous spin kick and over hook right hand, gsp plays the game too safe and only does enough to stay the champ and no i do not think he is the true p4p king no doubt he is one of the best tho, he is just an exceptionally talented athlete and martial artist for his time
