Brock Purdy player props

Brock Purdy Over 1.5 passing touchdowns (-115 via DraftKings) ⭐⭐⭐⭐

Mr. Irrelevant threw at least two touchdown passes in his first seven games as a starting quarterback. That streak was snapped in Week 2 when Purdy was held off the board against the Rams.

Purdy has appeared in one Thursday night contest, and he threw for two touchdowns against the Seattle Seahawks.

Now he faces a Giants defense that's surrendered just one passing touchdown in two games. New York prevented Dak Prescott from completing a six-point pass. However, the Giants did allow Joshua Dobbs and the Cardinals to connect with Marquise Brown for a score.

Brock Purdy longest completion Under 35.5 (-115 via BetMGM) ⭐⭐⭐⭐

Purdy has completed 36 passes through his first two games, with the longest being his 31-yard connection with Jauan Jennings during Week 2 against the Rams. His second-longest fell even more off of this mark (a Week 1 completion to Brandon Aiyuk for 23 yards). Purdy has completed just three career regular-season passes that have exceeded this total.

New York has only given up one catch for 34-plus yards in 2023. CeeDee Lamb snagged a 20-yard pass from Prescott and turned upfield for another 29 yards in Week 1. In 2022 the Giants allowed an average of 10.9 yards per completion while surrendering just three passes of at least 36 yards.  

Brock Purdy Under 28.5 pass attempts (-115 via bet365) ⭐⭐⭐⭐

Purdy has attempted 29-plus passes in just three of his eight regular-season starts. He also topped this mark in the two playoff games Purdy started and completed.

The 49ers have run the ball on 62 of their 120 offensive plays in 2023. That's eight more than the 54 passes Purdy has attempted.

Prescott attempted just 24 throws against the Giants in Week 1. Then Joshua Dobbs put the ball in the air 31 times while facing New York's defense. Both teams enjoyed success on the ground in their matchups. There's a clear path for Christian McCaffrey to get more touches, leaving Purdy with fewer opportunities to throw.
