1. Brees can afford to make a few mistakes and still win the game
There used to be a time, when Drew Brees threw an interception it would be a devastating error that would have ramifications for the entire game. Those days are over as despite giving up 17 points on three Saints turnovers, the Saints defense was still stout enough without Jabari Greer to limit the Niners offense to just three more points. Brees was able to get back on track and mount a comeback.
Brees is already a crazy perfectionist, but at least he has a bit of flexibility when he is out there trying to make plays. It also gives head coach Sean Payton extra confidence with his play-calling because he knows Rob Ryan and the defense have his back.
