Bo Nix or Brock Purdy: Who Should You Start?

The call

• The 16.2 projection and QB16 consensus rank put Nix just outside the 12-team starter line — he's a fill-in, not a set-and-forget play.
• A 20.0 implied team total is the real drag: Denver isn't projected to clear the low 20s, which caps the passing-touchdown ceiling even with full-game volume.
• The DvP composite lists KC 9 of 32 (softest = 32), but it's a 0-game sample at 0.00 confidence, so treat the matchup read as noise rather than a hard downgrade.
• Tip factor: a 2.5-point deficit means dropback volume if Denver trails — if your alternative is a QB with a higher team total, sit Nix; if he's your best arm, the floor is playable.

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.
