Two NFL preseason games take center stage on Sunday. Ben Johnson makes his head coaching debut when the Chicago Bears host the Miami Dolphins at 1 p.m. ET, followed by the New Orleans Saints traveling to take on the Los Angeles Chargers at 4:05 p.m. ET. The Chargers have already played one preseason game, dominating the Detroit Lions in a 34-7 victory in the NFL Hall of Fame Game. Los Angeles running back Kimani Vidal recorded nine carries for 37 yards and two touchdowns against Detroit, but should he be included in your Sunday NFL DFS lineups? 

Meanwhile, the Saints will be in evaluation mode as one of the most closely watched quarterback battles of training camp unfolds. Tookie Tyler Shough is battling second year players Spencer Rattler and Jake Haener to be the starter in New Orleans. Should any of New Orleans' quarterbacks make it into your Sunday NFL DFS lineups, or are there better QB options to consider for your Sunday preseason NFL DFS picks and stacks?

Top NFL preseason DFS picks for Sunday

One of Kaylor's top DFS picks for Sunday is Chargers quarterback Trey Lance. Things haven't gone exactly as planned for the former No. 3 overall pick in his four-year NFL career, but Lance's raw ability is undeniable. In last week's Hall of Fame Game against the Detroit Lions, Lance completed 13 of 20 passes for 120 yards and two touchdowns.

Lance is competing with veteran Taylor Heinicke for the Chargers' backup quarterback job. Heinicke is scheduled to start against the Saints on Sunday, but Lance is slated to see extensive playing time in the second half of the game -- which will likely come against New Orleans' backups. Kaylor believes Lance will have ample opportunity to replicate his performance in the Hall of Fame Game against the Saints on Sunday.

Another part of Kaylor's Sunday NFL DFS strategy includes rostering Bears running back Ian Wheeler. The former undrafted free agent became a fan favorite during Chicago's 2024 training camp, but suffered a torn ACL that ended his rookie season early. Wheeler is once again healthy, and has high end speed that makes him a home run threat every time he touches the ball.

Wheeler is battling several players for touches and ultimately a roster spot in Chicago. His speed and ability as a receiver make him an intriguing DFS option at this point in the preseason.
