Why Brock Purdy
Start· mediumStarting QB and offensive engine. Quick-processing rhythm passer with mobility, thrives in Shanahan play-action scheme.
QB12 with a 29.0 implied team total and added rushing upside; the 49ers are 11.5-point favorites vs ARI, so he's a solid QB1 start.
- ARI ranks 13 of 32 against QBs (a middle-of-the-road matchup, 2-game sample).
- Vegas implies 29.0 team points as 11.5-point favorites.
- Listed QB on the latest depth chart with a 93% snap share.
The call
- Vegas loves this spot: San Francisco's 29.0 implied total is a strong scoring environment, and a 20.8-point projection at QB12 sits right on the QB1 line in 12-team leagues.
- Rushing adds a floor. ESPN noted Purdy scored a rushing touchdown and ran for 30 yards last Sunday, which cushions any passing dip.
- The matchup reads neutral: ARI ranks 13 of 32 in DvP, but that's a 2-game sample with 0.00 confidence, so it shouldn't move the call either way.
- Main risk is the -11.5 spread. A blowout could shift volume to the run game late, which caps his ceiling more than his floor. No injury designation.

Why D'Andre Swift
Toss-Up· lowRB1 and lead back. Explosive one-cut runner off 1,000-plus rushing yards with steady passing-game usage.
RB21 at 12.8 projected with a 63% snap share is a borderline RB2/flex; a neutral DvP (12 of 32) on a 2-game sample gives no edge either way.
- PHI ranks 12 of 32 against RBs (a middle-of-the-road matchup, 2-game sample).
- Vegas implies 24.0 team points as 1.5-point favorites.
- Listed RB on the latest depth chart with a 63% snap share.
The call
- Role is solid but not bell-cow: a 63% snap share and 11% target share over 2 games give him steady PPR volume without dominating the backfield.
- The matchup read is noise. PHI ranks 12 of 32 in DvP composite, slightly tougher than average, but on a 2-game sample with 0.00 confidence it shouldn't move the needle.
- Game script is neutral-to-favorable. A 24.0 implied team total and -1.5 spread point to a competitive game with scoring chances and no blowout risk to his workload.
- What tips it: start him as an RB2/flex over lower-floor options in the RB24+ range. Sit him for any back ranked comfortably inside the top 20. The Achane vs. Swift headline is an unverified betting note, not usage news.
