Brock Purdy or Jayden Daniels: Who Should You Start?
2026 Week 1 · deterministic head-to-head · Verdicts based on PPR scoring.
Start Daniels — the consensus rank and projection edges are too wide to ignore.
Jayden Daniels is the higher consensus play (QB4 to QB12) and projects 16.8 to Purdy's 15.5. Purdy's edge is the game script, 22.8 implied points to 20.5. The gap is narrow.

Why Brock Purdy
Toss-Up· mediumStarting QB and offensive engine. Accurate rhythm passer with quick processing and play-action efficiency in Shanahan's system.
QB12 at 15.5 projected is the exact last starting slot — locked-in 98% snap role, but a 22.8 team total caps the ceiling vs LAR.
- Vegas implies 22.8 team points as 3.0-point underdogs.
- Listed QB on the latest depth chart with a 98% snap share in 2025.
The call
- Consensus QB12 with a 15.5-point projection puts Purdy squarely on the QB1/QB2 line in a 12-team league — he's a starter only if your alternative is worse than mid-teens.
- Role is not the question: 98% snap share over nine games means full-game volume and every dropback in the offense runs through him.
- A 22.8 implied team total is middling, and a 3.0-point spread points to a competitive script rather than the pass-heavy shootout Purdy needs to clear 20.
- Tipping factor: if the Niners land on the wrong side of that field-goal spread and have to throw to catch up, start him; if you roster a top-8 QB with a softer matchup, sit him.
Why Jayden Daniels
SitFranchise starting QB. Dual-threat passer with elite mobility and rapidly developing pocket game as the offense's cornerstone.
