Brock Purdy or Patrick Mahomes: Who Should You Start?

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.

The call

• The projection is the story: 15.5 points and a QB18 consensus rank put him in streamer range, not automatic QB1 territory, with a 22.5 implied team total capping the ceiling.
• Denver grades middle of the pack at 14 of 32 vs the position, and that composite comes off a 0-game sample with 0.00 confidence — no matchup edge to lean on either way.
• The Questionable designation is the concrete risk; if he's cleared and takes a full workload as the locked-in QB1, his ceiling still beats any replacement-level starter.
• A -2.5 spread points to a tight, competitive script, which is fine for volume — this tips to start the moment the injury report clears him, and to sit if he's limited or trending down.
