This is not an attempt to suggest the rating system is more accurate than gambling odds. Gamblers can analyze each fight individually, while the rating system uses a variety of mathematical routines to supply a primary fighter rating that is focused on ranking recent achievement, with a secondary priority of gauging future expectation.
With that said, there are some caveats to using the rating vs. odds comparison straight-up — the “Gotcha” list:
- System inability to project the exact effects of a recent divisional change.
- System inability to project the exact effects of recent inactivity.
- Poor matchmaking / limited careers / “changing of the guard”.
- Notable home advantage.
- System inability to project style differences.
- System inability to factor in bad judging decisions.
But this stuff (especially #5) is pretty much common sense. We try to partially factor in #1-#3 when we compute the ratings, but #5 and #6 is something that the human can factor in, that the system can’t. For the sake of these articles, we’ll attempt to factor in #4 when relevant. Home advantage can have a slight effect, but likely not enough to sway the “I’d bet on” decision.
Experienced gamblers know that it’s not about being right the most, it’s about making the most money. So in the usual table, I’ll add the “I’d bet on” column and analyze the rating/odds gap plus points #1-4 that I listed above.I’ll leave #5 and #6 to the fully subjective analyses (except for when Leonard Garcia is involved for #6) — of which I’m sure there will be plenty.
The gotchas aren’t necessarily comprehensive, but I have noted them as I come across them and when they are considered in the decision.
Having said all that, let’s get started:
Ratings vs. Odds
|Fight||Odds Favorite||Rating Favorite||I’d bet on||“Gotchas”|
|Magny vs. Manley||Magny (-161 / Small)||Magny (1.46x / Moderate)||PASS||#3|
|Robertson vs. Jardine||Jardine (-160 / Small)||Robertson (1.48x / Moderate)||Robertson|
|Bermudez vs. Grice||Bermudez (-412 / Large)||Grice (1.06x / Pick ‘Em)||Grice|
|Stout vs. Fodor||Fodor (-154 / Small)||Stout (1.02x / Pick ‘Em)||Stout|
|McGee vs. Neer||McGee (-293 / Moderate)||McGee (1.01x / EVEN)||PASS||#1|
|Chiesa vs. Kuivanen||Chiesa (-206 / Moderate)||Kuivanen (2.20x / Large)||PASS||#3, #4|
|Schaub vs. Johnson||Schaub (-145 / Small)||Schaub (1.24x / Very Small)||PASS|
|Koscheck vs. Lawler||Koscheck (-461 / Large)||Koscheck (1.76x / Moderate)||PASS||#1|
|Faber vs. Menjivar||Faber (-376 / Large)||Faber (3.02x / Very Large)||Faber|
|Machida vs. Henderson||Machida (-240 / Moderate)||Machida (1.21x / Very Small)||PASS||#2|
|Rousey vs. Carmouche||Rousey (-1149 / Massive)||Rousey (3.03x / Very Large)||PASS||#3|
Now, to the results — given the odds above:
The PASS suggests that the odds and ratings difference are nearly identical and/or there are too many gotchas, so neither fighter is a good bet. This particular card has a ton of question marks.
Favorites to consider: Faber is the only favorite worth a bet and a small one at that.
Underdogs to consider:
Stout over Fodor – 50/50 per the odds, so Stout serves as a minimally good value.
Robertson over Jardine – A fairly strong disagreement between ratings and odds. Fairly good value on Robertson.
Grice over Bermudez – A huge divide between the rating difference and the odds. It is quite rare to see this without any major “gotchas”.
