This week
Jalen is on the road against JAX. We project 240.9 passing yards, 27 rushing yards. The number comes out of a drive-level simulation of the game rather than a season average — it asks how many possessions his side is likely to get, what they do with them, and how much of that flows through him.
How much he's on the field
Jalen has averaged 98% of his team's snaps across 20 games. That's a full-time role. Snap share at this level is the most stable input we have — it changes slowly, and it survives a bad game in a way that yardage never does. Opportunity is the first thing the model reads and the last thing it gives up on — production without snaps is noise, and snaps without production usually corrects.
What kind of quarterback he is
Jalen has completed 363 of 580 (63%) for 3953 yards, 33 touchdowns and 9 interceptions — 6.8 yards an attempt. He's also run for 478 yards, which matters more than it looks: rushing production is the most reliable floor a quarterback has, because it doesn't depend on anyone catching anything. Yards per attempt is the number to watch: completion percentage rewards checkdowns, and a quarterback can complete 70% of his passes without ever threatening anybody.
His last 5 games
Over that stretch Jalen has 1000 total yards. In a sport with seventeen games, a five-game window is closer to an anecdote than a trend — which is why usage, not this, anchors the number.
How the model reads him
The number on Jalen is a share of a simulated game. First the matchup: possessions, field position, how each offense is likely to move. Then his slice of it, set by usage rather than by reputation. How those pieces are weighted is ours and gets re-tuned against results; the output is published and graded, which is the half you can check.
What we'd flag
Football's sample sizes are brutal — seventeen games a season means a "trend" is often four data points. Injuries and game script move usage more than talent does week to week, and a blowout can erase a starter's second half.
