Who Should I Start? Justin Herbert or Brock Purdy

Los Angeles Chargers quarterback Justin Herbert will play in his first career preseason game on Saturday against the Los Angeles Rams. Head coach John Harbaugh said the plan is for offensive and defensive starters, and Herbert will play "a series or two." While Herbert is viewed by many as one of the top quarterbacks in the NFL, his fantasy floor and ceiling took hits last season in Greg Roman's run-first offense. After throwing for at least 4,336 yards in the first three seasons of his career, the Oregon product tallied just 3,870 passing yards in 17 games a season ago. While he has a ton of upside in shootout game conditions, Harbaugh and Roman are unlikely to transition into a high-flying passing attack.

San Francisco 49ers head coach Kyle Shanahan said that he expects to play quarterback Brock Purdy and some of the other starters in the team's second preseason contest this Saturday against the Las Vegas Raiders. Purdy did not play in the preseason opener last Saturday against the Denver Broncos, so this will be his preseason debut this year, although he probably won't play more than a couple offensive series. The 25-year-old still has low-end QB1 potential with Shanahan running the offense and running back Christian McCaffrey in the backfield, but it's also concerning that San Fran's receiving corps is so beat up right now -- Brandon Aiyuk (knee) is on the PUP list and Jauan Jenninngs (calf), Jacob Cowing (hamstring) and rookie Jordan Watkins (ankle) are all hurt. Purdy's rushing ability gives him a higher floor for fantasy, even if the Niners' offense doesn't fully bounce back.
