The Week 1 NFL preseason schedule comes to a close with two games on Sunday, August 10. The Chicago Bears (-3) host the Miami Dolphins at 1 p.m. ET, and the Los Angeles Chargers (-0.5) host the New Orleans Saints at 4 p.m. ET to close out the day. All four teams are expected to rest the majority of their established starters, but the Saints quarterback competition will take center stage as one of the most closely watched position battles in the league during training camp.

Should any of the New Orleans quarterback contenders be a part of your Sunday NFL DFS lineups? Or should you look at other quarterback options in your preseason NFL DFS picks and NFL DFS stacks? Spencer Rattler to throw a TD pass on his first offensive drive is priced at +700 on DraftKings Sportsbook.
