Can anyone guess ways to continue to be successful with Brees?

I guess what I'm also asking is had the negative plays by Cooks and the block in the back penalty not happened and the Saints went on to win the Superbowl would anyone want him back for an encore?
Do we win the Superbowl? If we did, the point is mute because he would retire. Getting there is too hard, as we know from the past FOUR years. The team and my city, with all due respect, are bigger than Drew. I'm really not trying to bash Drew or deny his franchise greatness but it's time man.
