The problem with asking plain AI

Same question. Two different answers.

We asked a settled scoring question — a 2024 defense's fantasy points — to off-the-shelf AI and to StatsDeck. Off-the-shelf quietly dropped two safeties. In a head-to-head week, that two-point gap is the difference between a win and a loss.

Off-the-shelf AI

"How many fantasy points did this defense score that week, standard scoring?"

8.0 1 sack · 1 INT
1 fumble recovery
points-allowed tier ✓
— dropped 2 safeties (+2 each)

Confident. Clean-looking. Off by two points.

StatsDeck in Claude

Same question, your league's exact scoring rules.

10.0 1 sack · 1 INT
1 fumble recovery
points-allowed tier ✓
+ 2 safeties counted (+2 each)

Verified against the play-by-play record.

Why StatsDeck

Three things plain AI can't do for your team.

Anyone can recite last year's box score. StatsDeck does the part that actually decides your matchup.

Scoring you can trust

Every answer is computed against your league's real rules — PPR, custom DST tiers, kicker distance bonuses — and checked against the source record. No silently dropped safeties.

This week, not last year

StatsDeck knows what's already played, what's been ingested, and what hasn't — and tells you "data as of" so you're never acting on stale or made-up numbers.

Knows your roster

Connect your Sleeper league and ask about your team and your waiver wire. Start/sit and trade calls in the context of who you actually own.
