Fantasy Football Start’em, Sit’em: C.J. Stroud, Caleb Williams, J.J. McCarthy

Start em or sit em? Fantasy football start or sit decisions can be excruciating.

Fantasy Football Start’em, Sit’em Lineup Advice: Quarterbacks

C.J. Stroud (QB)

Last year was disastrous for Stroud as he tumbled from the QB7 in fantasy points per game to the QB28. Everything that could have gone wrong did. His offensive line imploded. Nico Collins was in and out of the lineup, while Tank Dell and Stefon Diggs were lost to season-ending injuries. Stroud didn’t help matters with the fifth-highest time to throw and the 15th-highest pressure-to-sack ratio. Stroud will operate behind a retooled offensive line in 2025 that honestly couldn’t be worse than what he dealt with last year. The skill player cabinet has been restocked. Stroud should post solid numbers in Week 1 against a secondary that, in Weeks 10-18 last year, allowed the eighth-highest success rate per dropback, 11th-highest EPA per dropback, and was 16th in passer rating.

Caleb Williams (QB)

Let’s call a spade a spade here. Caleb Williams had a VERY tough rookie season. The ballyhooed savior of the Windy City didn’t exactly have the start to his career that many people hoped for and hyped. Williams was the QB21 in fantasy points per game, which was aided greatly by his legs (seventh in rushing yards among quarterbacks). Williams was the QB12 in expected fantasy points per game, so the disappointment was very real. When we discuss what he did as a passer, the true tragedy becomes apparent. Last year, among 40 qualifying quarterbacks, Williams ranked 34th in yards per attempt, 24th in CPOE, and 26th in highly accurate throw rate. Williams had the ninth-highest off-target rate and the second-lowest catchable target rate (only Anthony Richardson was worse). The Bears have added a TON of personnel to help Williams find his footing in year two with offensive line upgrades, a strong play-caller (Ben Johnson), and the additions of Luther Burden and Colston Loveland. Williams looked good in brief preseason action, but we need to see him do it in the regular season. Asking Williams to hit the ground running against a Brian Flores defense in Week 1 is probably asking too much, though. Last year, Minnesota blitzed at the highest rate in the NFL while also ranking sixth in pressure rate. The Vikings also kept quarterbacks in check, giving up the 12th-fewest yards per attempt and passing touchdowns and the second-lowest passer rating.

J.J. McCarthy (QB)

Yes, I know we haven’t seen J.J. McCarthy play outside of an abbreviated preseason sample last year, but I’m a big believer in his talent and Kevin O’Connell to get the best out of him. The Vikings remain loaded with skill players and added to the offensive line this offseason to give their new signal caller all the time in the world to dice up opposing pass defenses in 2025. Sam Darnold (yes, that Sam Darnold) finished as the QB9 in fantasy points per game last year. In his final collegiate season, McCarthy ranked inside the top 12 FBS quarterbacks in passing grade, adjusted completion rate, yards per attempt, adjusted completion rate with downfield throws, and against pressure. McCarthy will have a tough assignment against a new-look Bears pass defense this week. New defensive coordinator Dennis Allen will install a two-high heavy scheme. In two of his last three seasons with New Orleans, his defense was top eight in two high usage (seventh & eighth), utilizing it 51.7-52.1% of the snaps. This should mesh well with Chicago’s defense. Last year, when utilizing two high, Chicago held quarterbacks to the eighth-lowest CPOE, the third-lowest passer rating, and the seventh-lowest yards per attempt.
