Game Analysis

No book odds exist, so we lean on Omega's Poisson/ELO line (HOU +113) and Bayesian fusion (55% win probability). The gap creates a +17% EV on Houston ML, but with degraded data (56% signal availability), low model agreement (9.2% spread), and a 48.4% sport win rate, confidence is capped at LEAN. Whales on Polymarket align with home, but only 28 wallets and top profit $0 — not enough to boost conviction. Spread pick'em offers small +3.4 EV. Skip total (EV negative). This is a data-limited game: bet small or skip.
