Strategic Angle: Why the Data Defies the Narrative
The authorās prediction hinges on Bonfimās takedowns neutralizing Thompsonās striking. While plausible, the EV math screams otherwise. Bonfimās implied 82% chance is absurdly inflated given:
1. Thompsonās 35% underdog win rate in MMA (vs. 81.97% implied).
2. Thompsonās recent struggles (2-4 in last 6 fights) vs. Bonfimās finisher pedigree (9 KOs in 13 wins).
The Numbers Say: Bonfimās line is overpriced. Thompsonās line is a diamond in the rough.
Final Verdict: Bet the Underdog
Pick: Stephen Thompson (+4.50)
Why:
- The EV model favors Thompsonās adjusted 28.61% win chance vs. his 22.22% implied.
- Bonfimās 82% implied is unsustainable; even a 73.48% adjusted line is too rich.
- Thompsonās takedown defense (63%) and striking defense (62%) could frustrate Bonfimās aggressive style.
Bonus Bet: Over 2.5 Rounds (-3.5 spread)
- Bonfimās 35-second finisher reputation vs. Thompsonās durability? Over 2.5 rounds (-3.5) at -140 (implied 58.33%) is a hedge. If the fight goes past Round 2, Thompsonās stamina could shine.
TL;DR: The crowd loves Bonfimās āfinisherā label, but the math loves Thompsonās undervalued line. Bet the underdogāunless you literally love being average.
