Looked pretty much exactly the same to me. I think this is a bit of a placebo affect to be honest. Rogan kept stating over and over how big he thought GSP looked and then everyone else "sees" it aswell. compare pics of the staredown and I doubt you'll see any difference.
Beat me to it. Yeah this. I was in a bar and I live in Canada, so I never heard a word Rogan said the entire fight, and I never once thought he looked bigger. He looked the way he always looked to me. Condit was bigger than GSP, never mind Silva.
