What does G.O.A.T mean?

From Flickr.com By: unknown

What does G.O.A.T mean? G.O.A.T is an acronym that stands for the greatest of all time. There have been many of them over the years of the NFL but I chose what I think are the best players of all time. Not only have all the G.O.A.Ts of the sport exceeded the standards, but I think all the players to the right have gone above and beyond and have transformed the NfL forever.
