Videogames Make Traditional Super Bowl Predictions

Thanks to Reuters for its article discussing videogame-based predictions for this weekend's Super Bowl. The piece explains: "Days before the real football championship is contested, Carolina Panthers wide receiver Steve Smith has beaten the New England Patriots' wide-out Troy Brown 29-21 in a head-to-head video game matchup." The match was played on Sony's NFL GameDay 2004, and it's noted: "In the first eight years of the event, the winner of the electronic showdown went on to hoist the Vince Lombardi Trophy as the Super Bowl champion." Elsewhere, 1UP has done its own Super Bowl predictions on four different football videogames, and the final results also favor the Panthers.

I suspect the video game companies have rated the patriots players a bit low what with the real life team being on a 14 game winning streak and all. I would guess that the reason the games have been fairly accurate predictors in the past is because they have done a good job capturing the varrying skill levels of the players, but for some reason the patriots I watch on TV seem vastly better then the patriots I control in Madden.

LIONS IN 2006!

Mangled English Hurt Brain

[\\]

The following few sentences on the NFL Gameday 2004 page are making my brain hurt:

At the end of the second half, the score is 7 - 6. The Panthers are not content to go into the locker room with the score so close. With less than 3 minutes left, they pull out some play calling that is so pass-friendly you'd think the Colts were on the field.

The end of the second half is the end of the game, and if it really means the end of the second quarter/first half, then why is there all of a sudden three minutes left and both teams score again to make it 14-9? For once I'm sure this isn't a product of my being half asleep, this actually MAKES NO SENSE. ARGH! For the love of god, 1up needs an editor.

Bill Simmons wrote an article on the game, as he was there. It can be read here. In it, he says that they were playing 3 minute quarters.

Editors? We don't need no stinkin' editors!

Results weren't supported by tests

So I read the article about the 4 different games they tested with. The problem is that the games really weren't reflective of the real life teams. For example, in two of the games the Panthers were a passing team. Then they somehow conclude the Panthers are a lock? I don't think so. Video games may try to predict football games, but I still trust the predictions from Vegas much more.

but I still trust the predictions from Vegas much more.

Problem with this is that when Vegas sets the line, they're not so much predicting the outcome of the game as they are predicting the betting tendencies of the gamblers. E.g. "New England -7" is calculated to ensure that roughly half the bettors will take Carolina, half will take New England.

If they set the spread too low, e.g. "New England -6.5," too many people would bet on New England, so that if New England wins by a touchdown the Vegas books would loose money...

This is also why the line changes if too many people start betting one team. It's kind of like the stock market, insofar as the odds have *something* to do with the teams' projected performance, but have much more to do with the publics' perception of the value of the bet.

At least this is how I understand the system to work. (IANA gambler, though.)

Re:Results weren't supported by tests

I am a professional handicapper and can confirm and elaborate.

Bookmaking in the US is based on -110 odds. Whatever side you want to back against the spread, you're risking $110 if you lose to win $100 if you win (there are discount books offshore/online; Pinnacle out of Curacao generally offers -105). Thus, as long as the betting on both teams breaks down in the 47.5% to 52.5% area, the bookmaker is guaranteed a profit whatever happens. At anything outside that range, the bookmaker is betting on the outcome, as they stand to lose money if the heavily bet side wins.

There's more to it than simple balanced action. The line opened in Vegas and offshore at NE -6.5 and got steamed up to -7. It's highly unlikely though, that any additional action would push it to 7.5 (at least at reputable books [see below]).

The reason is key numbers. You can generate pretty much every realistic number of points scored by an NFL team with a function like s(x,y,z)=3x+7y+z, where x, y, and z are all integers greater than or equal to zero, their sum is less than 8, and z is less than x+y. The realistic score differences are thus differences between s-values for two ordered triples satisfying those constraints. Analysis of this will confirm that 3, 4, 6, 7, 8, 10, 13, and 14 are commonly encountered score differences, with 7 and 3 being especially common.

The result is that bookmakers will require massively unbalanced action to move off of a key number (3, 4, 6, and 7) and to a lesser extent to move onto a key number. At those numbers, bookies are much more willing to gamble, as the balanced action around those numbers is a huge risk.

This risk is called "getting sided" or, even worse, "getting middled".

Imagine that you bet the Patriots -6.5, along with enough of the betting public, to push the line to 7. You buyback Panthers +7 at the same stake level. Let's say you're risking $1100 on both ends. If the Patriots win by 8 or more, Pats -6.5 wins, Cats+7 loses, for a net loss of $100. If the Patriots lose or win by less than 7, the reverse happens. But if the Patriots win by exactly 7 (which is common), your Panthers bet pushes (nothing gained, nothing lost) and the Patriots bet wins. Essentially you've hedged your way into betting at +1000 that the game lands on 7. This is "siding".

It's not difficult to see that the book gets mauled in this situation if everybody's doing it.

Now imagine that Patriots action pushed the line to 7.5. Now, both bets hit if the Patriots win by exactly 7. This is "middling".

You may recall a Monday Night Football game between the Giants and Bucs earlier this year. The line was Tampa -5.5 and steam on Monday pushed it to 6. Late in the game, Giants trailing by 4, they take a safety, giving Tampa two points. Al Michaels (who almost definitely bets on the games; it's not difficult to tell when he has OVER or UNDER) said, "That noise you just heard in Vegas wasn't an earthquake."

Funny story.

The Detroit Lions were my 'Dark-horse' pick this past year. Because when they were getting their asses handed to them the year before, they never were 'ok' with it. They had a lot of speed, but mostly a good attitude. So when I took my friend to the Seahawks game this year, I was like, well there's really no reason we should lose, but the Lions are one of those teams that could take advantage of the open door. Seahawks are kicking ass, skiping names. The crowd of course is cheering, and some people are acting like the game is in the bag. I turn to my buddy and go, the games far from over, Detroit's a deep threat on every down. Lions take their next offensive snap, nine seconds, endzone.

We out here, in Seattle, know you guys are better than your record. We're still happy to kick your ass, but when you're not playing our boys we want the best for you.

Stupid

[pudge]

How many of these games would have predicted the Patriots would win 14 games in the regular season? Not a one. And if they can't do that, why trust them now?
