Brock Purdy or Jaxson Dart: Who Should You Start?
Preliminary board2026 Week 1 · deterministic head-to-head · Verdicts based on PPR scoring.
Verdicts sharpen as practice reports land.
Start Jaxson Dart: rushing access and matchup outweigh Purdy's steadier workload
Dart gets the call because his dual-threat role can turn the softer Dallas matchup into points even if the passing game is uneven. Purdy's near-total snap involvement and role as San Francisco's offensive engine give him the steadier floor, but his lower standing and less favorable matchup leave less room for a ceiling game. The edge is meaningful without being enormous for quarterbacks: Dart's risk is that his aggressive style creates volatility, while Purdy remains the safer fallback if you prioritize stability.
What flips it: A late change to Dart's starting role.

Why Brock Purdy
Sit· mediumStarting QB and offensive engine. Quick-processing rhythm passer with mobility, thrives in Shanahan play-action scheme.
QB18 consensus with a 15.5 projection and just a 22.8 implied total — outside the top-12 starter range in a 12-team league.
- Purdy's command of the 49ers offense gives him a dependable path to production even without a premium matchup.
- His near-total snap involvement is the strongest argument against treating him as a clear fade.
The call
- Consensus has him at QB18 for 15.5 points; in a 12-team single-QB league that's below the replacement line you can stream against.
- A 22.8 implied team total and a 3-point underdog spread cap the ceiling — this projects as a moderate-volume, moderate-scoring game rather than a shootout.
- The Rams' defense-vs-QB composite sits 18 of 32, dead-middle, and it's built on a 0-game sample (confidence 0.00), so there's no matchup edge to bank on.
- He's the locked-in starter with no injury designation, so this is purely a ceiling call — if you're thin at QB he's a fine floor play, but a top-12 streamer beats him this week.

Why Jaxson Dart
Start· mediumStarting QB and franchise building block. Dual-threat with designed-run production and aggressive downfield arm.
QB9 consensus at 18.5 projected with a soft Dallas matchup (28th of 32 DvP) and a one-score script that keeps him throwing.
- Dart has two scoring avenues through designed runs and downfield throws, giving him more ways to beat his baseline.
- The Dallas matchup supports his ceiling, especially in a close game that should keep his offense engaged.
The call
- Consensus has him as the QB9 at 18.5 projected points — that is a clear starter in a 12-team league, not a streamer flier.
- Dallas grades 28th of 32 in defense-vs-QB composite; the sample is thin (0 games, 0.00 confidence), but nothing in the sheet points to a tough draw.
- A 1.5-point spread and a 23.5 implied team total mean a competitive game with meaningful volume — no blowout risk that shrinks his dropbacks.
- He's the locked-in QB1 on the depth chart with no injury designation, so the floor is a full workload.
