You know the summertime off from football has begun when NFL Network or ESPN or some other sports outfit is putting together their "Greatest Lists of All Time."The NFL Network (which I watch more often than the nightly news) has come up with a piece where all 32 teams has a Mt. Rushmore of sorts --- the greatest players to play the game in that city. While fans beat each other over the head deciding if Brett Favre and Aaron Rodgers both should be on the side of Lambeau Field, other teams don't have the same pedigree as others.Sorry, Carolina, Jacksonville and Houston.But the topic of who would make it on the NFL scene of all time brings about great debate and even fighting words among sports writers nationwide.Here is a list of my four and others who could have replaced them. Remember, please, that this is an opinion piece and is comprised to develop debate. I would love to hear what all of you have to say and offer.
