I personally think he would be #2. Losing to Silva and Page make it hard for me to call him GOAT. I don't hold his loss to Shields against him because its pretty obvious from his performance that he had a back injury and I am sure if they had a rematch Shields would be k.o'd. He is a hell of a fighter and I agree he is the most decorated MMA fighter.
He is also in my top 3 for fighters I would like to have a beer with
Favorite fighters: GSP, F. Griffin, Jon Jones, Nick Diaz, Carwin, Ken Flo, Leben
