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.
