Believe it or not, it's actually not so easy to win multiple Super Bowls with a top QB unless you're Bill Belichick and can build a full roster. How many Super Bowls did Tony Dungy win with Peyton Manning, Payton with Brees, McCarthy with Rodgers? All just won a single championship.
The Packers have been needing more quality talent for about 5 years now but when you have a great QB, you are usually able to win 10+ games a season so you're picking at the end of each round in every draft. It took Sean Payton three straight 7-9 seasons to finally be able to retool and put together the team they have now.
