Brees has been startable this season, but it seems as if his explosive days are over. The turnovers, like with Ryan, have been dragging down what would be above-average fantasy quarterback numbers. Brees has an interception in three of his four starts this season and has lost fumbles to go along with them.
The defensive-minded Atlanta head coach, Dan Quinn, has the Falcons seventh in the NFL in takeaways per game (2.0). If I had to bet, Brees will have at least one and probably multiple turnovers. This may limit the fantasy upside and production for Brees in Week 6.
A positive thing to note is that Thursday Night Football games have had plenty of points scored in them every week. There hasn't been a point total lower than 40 in any TNF game this year and the total has been over 50 twice. Brees should get his volume, but may not put up elite numbers the way he used to.
