### 5. Final Verdict
- Play: Petrino -3.5 AND Under 1.5 Rounds at -484.
- Rationale: Petrino’s tapout expectation makes the Under a lock, while the spread’s slight negative EV is offset by the Under’s +13.4% edge.
- Alternative: If you’re feeling spicy, take Lane +525 for a 27% chance to win $425 on a $100 bet. It’s a Hail Mary, but 35% of underdogs in MMA pull off miracles.

“Petrino’s heavyweight debut isn’t just a fight—it’s a physics experiment. Lane is the control group. Don’t cry when the experiment explodes.”
