NFL props, lines for Thursday, July 31
The starting quarterbacks will be a key factor in NFL DFS contests for Thursday’s Hall of Fame Game, especially since teams rarely play their starters in the first game of the preseason. Los Angeles has confirmed Trey Lance as its starter for this game, as the No. 3 overall pick from the 2021 NFL Draft tries to secure the backup spot this season. Detroit is expected to split quarterback reps between Hendon Hooker and veteran Kyle Allen, who are battling for a spot behind Jared Goff on the depth chart.
Betr has Lance’s passing yards total at 117.5, while Hooker’s total is significantly lower at 97.5 and Allen’s over/under is 92.5. Both teams are likely going to run the ball heavily throughout the game, and there are nine players with rushing yard totals at Betr. Detroit’s second-year running back, Sione Vaki, has the highest rushing yards total of that group at 32.5.
Other running backs to consider in NFL DFS contests include Detroit’s Kye Robichaux (31.5) and Jabari Small (28.5), along with Chargers running backs Kimani Vidal (24.5) and Jaret Patterson (20.5). There are also various receiving props to sort through before setting your NFL DFS lineups and using the top NFL DFS promo codes.
