People lose sight of the fact that, despite all of the media attention, hype, retirement watches, trips to Hattiesburg, etc.. he is one of (if not the) greatest QBs of all time and played year in and year out at a top 5 level for about 17 years.. What wouldn't we give to see Brees play at his current level or only slightly below for a whole other decade?
Farve took his team to 2 SB's and 5 championship games. He almost certainly would have another championship or two if GB would have bothered itself to have had a better defense around the turn of and early part of this decade.
