Brock Purdy or Lamar Jackson: Who Should You Start?

2026 Week 2 · deterministic head-to-head · Verdicts based on PPR scoring.

Lamar's rushing floor breaks the tie over Purdy's better game script

Start Lamar Jackson, but keep Brock Purdy in lineups; both are legitimate QB starts. Purdy has the better scoring environment, with San Francisco favored heavily and positioned for easy touchdowns, while Miami is only a middling matchup. The one-point projection gap is noise at quarterback, but Lamar's QB2 standing and dual-threat floor separate him, with early reviews of Baltimore's new offense backing the outlook (ESPN 2026-09-14). Purdy's upside is real and his game script is the call's biggest threat, but Lamar's risk is exposure to Baltimore's lower implied total rather than a weak role.

What flips it: A late Lamar availability downgrade.

Why Brock Purdy

Start· medium

Starting QB and offensive engine. Quick-processing rhythm passer with mobility, thrives in Shanahan play-action scheme.

20.7 projected points with a 28.5 implied team total — Purdy is a locked-in QB12 start even with a middling matchup on paper.

  • Purdy's favorite-game script can create rushing and easy scoring chances even if Miami's middling QB matchup holds.
  • His risk is volume: a comfortable San Francisco lead could make the offense conservative late.

The call

  • A 28.5 implied team total is among the week's highest, and Purdy is the unquestioned QB1 with no injury designation — the volume and scoring environment are there.
  • Miami's DvP composite sits 13 of 32, but that's off a 1-game sample with 0.00 confidence, so it's not a reason to fade a QB projected for 20.7.
  • The only real risk is the -10.5 spread turning into a run-heavy second half that caps his passing volume; even then, touchdown equity in a near-29-point offense keeps his floor fine for a QB12.
  • Start him over a typical replacement QB — the projection already prices in the matchup.

Start — every-week QB start at consensus QB2: NO is the 11th-softest matchup vs QBs, 27.0 implied team total.

  • Lamar's rushing and off-script creation protect his floor when New Orleans disrupts clean passing lanes.
