I don't think any of those metrics are that important for determining the GOAT. If your definition of GOAT is who was the most successful QB than SBs play a huge factor. However, if you are simply saying who is the best ever than none of those stats mean all that much. For example if Brady was drafted by the Browns in 2000 he never wins an SB. He is still just as good as he is now, but now all of a sudden he isn't in the GOAT conversation. I think to determine the GOAT you need to eliminate all outside factors and just figure out which QB had the best combination of Vision, football IQ, arm strength, accuracy, etc. That is the true GOAT. Basically if you plugged Montana, Unitas, Manning, etc all into the 2000 Patriots and had them play 20 seasons which QB would have ended up with the most SBs. Whoever that is, is the GOAT. I don't know who it is. It could be Brady for all I know, but that is my definition of the GOAT.
I am curious though. What changed your mind from yesterday when you said Brady was only arguably the best QB in recent times to your current opinion of him being the best player, hands down, in NFL history at any position.
