NFL prop lines for Saturday, Aug. 9

Some of the trending props at Sleeper Fantasy for Saturday include Cam Ward recording higher or lower than 54.5 passing yards. The Titans have confirmed that the No. 1 overall pick in the 2025 NFL Draft will start alongside most of the first unit on offense. Ward threw for 4,313 yards at Miami last season, but this will be a completely different environment as the Titans will balance the need to get him some work with the desire to keep him healthy, given that he's set to be the starter this season. 

Travis Hunter, meanwhile, has a higher or lower line of 25.5 receiving yards at Sleeper as the Jaguars face the Steelers. The 2025 Heisman Trophy winner is expected to play both ways this season, though he's listed as a starter at receiver and a backup at cornerback for the Jags. Hunter could be a bit of enigma for DFS players all season as the Jags will have to manage how many snaps he can handle and how that workload will be divided. 

It's not all about the rookies on Saturday, however. The Chiefs plan to play their starters for a quarter against the Arizona Cardinals, and that includes two-time NFL MVP Patrick Mahomes. His passing yardage total is 41.5 and he has a passing touchdowns higher or lower of 0.5, with the higher returning 1.05x.
