Excuse Me While I Wipe This Egg Off My Face…

I’ll have Fight Scores up on this blog as soon as I get the Fight Metric data. I also have plenty to say about the main event, but first I need to talk about my picks and FPR…

If you want to throw tomatoes at me for the VERY high-confidence projections for Chael Sonnen and Rory MacDonald, I don’t blame you. Part of me wants to throw tomatoes at myself.

There are clearly some flaws in my model and how I determine who will win fights. There is no excuse for coming out and saying Chael Sonnen had an 89 percent chance of beating Rashad Evans. Even though I said myself that I didn’t buy that projection, my model should never say that in the first place.

So there are no excuses. My picks straight-up really weren’t all that bad (8-4) but the problem is in the percentages. The fighters FPR recommended a bet on didn’t do well at all… accounting for three of the four losses. The fighters I recommended were 3-3 tonight but again, the two highest confidence picks went down in flames.

With that said I’ll say a couple things in my defense. This blog is based on stats and FPR in particular is based on Fight Metric stats. I defy you to go to the Fight Metric stats for Chael Sonnen, Rashad Evans, Rory MacDonald, and Robbie Lawler, and tell me with a straight face that the stats favor Evans and Lawler to win their respective fights. You can’t do it. The stats clearly indicate that Sonnen and MacDonald are better fighters.

Now, I get it. Statistics need context. Renan Barao’s statistics might be better than Joey Beltran’s, but that doesn’t mean Barao would beat Beltran in a fight. I would love nothing more than to break down each fighter’s statistics and separate them by weight class, by opponent, and by where the fight takes place (top position, bottom position, standing distance, clinch, etc.). Perhaps my model should have looked at what happens if Sonnen doesn’t take Evans down. If that was the case the model might have recommended a bet on Evans. It’s tough to say.

The problem is: I don’t have that data. It’s not available on Fight Metric. If I want to get that kind of data, I need to go through the tape of the fights and collect it myself. I don’t know about you, but I don’t have the time to do that for every fighter. I wish I did but I don’t.

The other problem is: the statistics are already so limited for most of the fighters already. When there is a small sample of data, taking segments of that data only makes things worse. In MMA the biggest obstacle to proper statistical analysis is a lack of data. It’s not a good idea to exacerbate that problem by only looking at portions of the already limited data I have.

Does that mean I shouldn’t make any changes? Obviously not. There are changes that absolutely have to be made to my model. I’m not 100 percent sure what those should be yet, but I have some good ideas. One thing is for sure – you’re not going to see as many fighters considered a 90 percent favorite to win from this point forward.

All of that said, FPR still has a very good overall record, both with straight-up picks (unless you think being ranked #23 on Sherdog is bad) and against the spread (although today put a major dent in that). I can’t revel in the good times and then panic and change everything during a cold streak. That’s just bad form.

So if you’ve lost faith in my ability to predict fights, I don’t blame you but even the best have an off night now and again. I don’t claim to be the best but I still think I can contribute valuable insight in the MMA community. Time to look “under the hood,” tighten some bolts, and come back with a better model next time. See you then.

    Shocking night. The Macdonald loss was the painful to me but hey, he’s the better fighter overall and could have won that fight easily if he hadn’t been so passive in the early rounds. After the third round almost KO punch it was way too late. He fucked up his tactics as i see, but please correct me if i’m wrong.

    and sry for my bad english.

      Your English isn’t bad at all, obraz. I was shocked by the MacDonald loss too and I feel exactly the same way you do. MacDonald was fighting “not to lose” instead of fighting to win. I don’t know what happened to the savage, attacking Rory MacDonald, but I’d love to have him back.

    He went to Tri Star. He attacked more before he switched gyms.

    thorouhly enjoy what you do here…i always read your write ups and they are very helpful……but i absolutely disagree on the chael sonnen /evans opinion…..sonnen is basically a one trick pony and if he can`t impose his wrestling acumen on his opponent,he`s done….granted,he`s done it vs some very solid fighters(anderson silva included)…but vs another top flite wrestler with advantages in striking(stand -up),speed and athleticism,this was an absolutely nightmarish match-up for sonnen,imo….he woukl have had to be the better wrestler(by a decent measure) to play his clinch,wrestling game on evans….he couldn`t….and he should never,ever step in the ring with phil davis….

    he`s an excellent promoter and if you aren`t a high level wrestler he can dominate….but vs other ,more well rounded athletic wrestlers,he`ll have problems….

    i understand your model is based on stats,but,in your own objective “eyeballing” of both guys,didn`t you feel that evans was absolutely a legit favorite?….i would have been surprised if he wsan`t….i know that many times you obsrve and point out flaws in the model and point them out to your readers(and do it well)….

    mcdonald was a shock here as well,but,i was happy to see a tough,fan friendly vet like lawler set himself up for one more chance at some lucrative paydays…the little russian impressed while he seemed to make elliott leery to engage(seems most of the russians are very willing to exchange and do quite well when they do)…young pettis will lose some he shouldn`t if he continues to readily go to his back as much as he does vs lesser competition…

    anywho,keep up the good work…really enjoy the work you put in…..

      Thanks Tony. When I look at the takedown stats I genuinely believed Sonnen could take Evans down. The takedown numbers were very similar between the two with Sonnen’s takedown offense being a bit better. Obviously that was a poor judgement on my part.

      Part of doing what I do is embracing the reality that sometimes I’m going to be wrong. I don’t mind being wrong once in a while. I just need to not be as wrong as I was with Sonnen.

      I’m tinkering with FPR and already liking some of the changes I’m thinking of. Stay tuned.
