WagerBird Write-Up · Jayson Tatum 3-Pointers Made (Under 3.5)

Full Dossier Unlocked
Write-Up Thesis

Tatum's attempt volume and ordinary shooting accuracy point toward a made-three total below the posted threshold.

01 · Fundamental Driver

Volume without excess makes

2.9 3PM · 8.9 3PA LAST SEASON — Tatum averaged 2.9 made threes on 8.9 attempts in his limited prior-season sample. That combination shows how a substantial perimeter workload can still produce a modest made-shot total when accuracy remains ordinary.

02 · Fundamental Driver

Recovery is allowed

1.5 3PM · 8.5 3PA · 17.6% — The opening two games contain 1.5 makes on 8.5 attempts at 17.6%, well below his prior 32.9% accuracy. A return toward that prior accuracy improves his shooting without requiring an unusually efficient perimeter night.

Red Team · Counter-Case & Risk Factors

Thesis Invalidation Risks

Tatum attempted ten threes in the latest completed game, so improved accuracy can defeat this position without a change in role. A close fourth quarter can keep the attempts coming instead of shortening his night.

Settlement Rule: CASHES JAYSON TATUM FULL GAME THREES UNDER 3.5 WITH THREE OR FEWER MADE THREES; NO PUSH.
