First Round Recap and Second Round Playoff Preview by the Numbers

“Now it is such a bizarrely improbable coincidence that anything so mind-bog-gglingly useful could have evolved purely by chance that some thinkers have chosen to see it as the final and clinching proof of the non-existence of God.

The argument goes something like this: `I refuse to prove that I exist,’ says God, `for proof denies faith, and without faith I am nothing.’

`But,’ says Man, `The Babel fish is a dead giveaway, isn’t it? It could not have evolved by chance. It proves you exist, and so therefore, by your own arguments, you don’t. QED.’

`Oh dear,’ says God, `I hadn’t thought of that,’ and promptly vanished in a puff of logic.

`Oh, that was easy,’ says Man, and for an encore goes on to prove that black is white and gets

himself killed on the next zebra crossing.”

-Douglas Adams The Hitchhiker’s Guide to the Galaxy

Let’s recap.

We’ve spent a lot of time together on this blog looking at what makes a team successful in the playoffs. We’ve seen some very interesting patterns. I’ve done some complicated math. An at the start of the playoffs, I decided to make some picks using what we know (or believe we know). Because to quote Feynman( The quote is from “Simulating Physics with Computers”):

I want to talk about the possibility that there is to be an exact simulation, that the computer will do exactly the same as nature. If this is to be proved and the type of computer is as I’ve already explained, then it’s going to be necessary that everything that happens in a finite volume of space and time would have to be exactly analyzable with a finite number of logical operations. The present theory of physics is not that way, apparently. It allows space to go down into infinitesimal distances, wavelengths to get infinitely great, terms to be summed in infinite order, and so forth; and therefore, if this proposition is right, physical law is wrong.

So an accurate simulation is possible just not very easy.

I do love a challenge

Let’s Review the relevant facts first:

It’s about to get math intensive here so if it’s your first visit (or if you need to bone up) that’s what the Basics are for.

How did I do?

Let’s see:

Eastern Conference Round 1

Series 1: Chicago vs Indiana: Win % @ Neutral Site: >70% for Bulls

The Numbers said:Bulls in 5

Home Team Win Margin 70% ++
W4 23%
W5 34%
W6 18%
W7 15%
L4 1%
L5 1%
L6 4%
L7 4%

My Prediction: Bulls in 4.

Result: Bulls in 5 (most likely predicted scenario at 34%)

The Numbers and I both had the Bulls right. I had the Lenght of the series wrong (the numbers did not).

Series 2: Miami vs Philadelphia Win % @ Neutral Site: just about 70% for Miami

The Numbers said:Heat in 5

Home Team Win Margin 70%
W4 23%
W5 34%
W6 18%
W7 15%
L4 1%
L5 1%
L6 4%
L7 4%

My Prediction: Heat in 5.

Result: Heat in 5 (most likely predicted scenario at 34%)

Everyone got this right.

Series 3: Boston vs New York Win % @ Neutral Site: I took 65%

The Numbers said: Celts in 5

Home Team Win Margin 65%
W4 17%
W5 30%
W6 18%
W7 18%
L4 1%
L5 3%
L6 7%
L7 6%

My Prediction: Celts in 6.

Result: Celts in 5 (4th most likely predicted scenario at 17%)

Got the series right but missed the length. The numbers came close to getting this one perfect too (and iffy call in game 1).

Series 4: Orlando vs Atlanta: Win % @ Neutral Site:About 68% for Orlando if I’m really,really nice to the Hawks and ignore their post All-Star collapse.

The Numbers said:Magic in 5

Home Team Win Margin 68%
W4 20%
W5 32%
W6 18%
W7 16%
L4 1%
L5 2%
L6 5%
L7 4%

My Prediction: Magic in 5.

Result: Hawks in 6 (5th most likely predicted scenario at 5%)

How do you outscore your opponent by almost two points a game with the best player on the court and still lose a series? Ask the Magic, they just did it.

Western Conference 1st Round:

Series 1: San Antonio vs Memphis Win % @ Neutral Site: 54% for Memphis.

The Numbers said: Grizz in 6

Home Team Win Margin 46%
W4 4%
W5 12%
W6 11%
W7 18%
L4 8%
L5 13%
L6 21%
L7 14%

My Prediction: Grizz in 7.

Result: Grizz in 6 (Most likely predicted scenario at 21%)

Again, me and the numbers both nail the result but the numbers get it spot on (I’m guessing you’re sensing a pattern here 🙂 )

Series 2: LA vs New Orleans Win % @ Neutral Site: 65% Lakers.

The Numbers said: LA in 5

Home Team Win Margin 65%
W4 17%
W5 30%
W6 18%
W7 18%
L4 1%
L5 3%
L6 7%
L7 6%

My Prediction: LA in 5.

Result: LA in 6 (2nd Most likely predicted scenario at 18%)

Never underestimate Chris F#$%ing Paul. I thought (and so did the numbers) he’d get one but he got two.

Series 3: Dallas vs Portland Win % @ Neutral Site: 60% Dallas.

The Numbers said: Dallas in 5

Home Team Win Margin 60%
W4 12%
W5 25%
W6 18%
W7 20%
L4 2%
L5 4%
L6 11%
L7 8%

My Prediction: Dallas in 7.

Result: Dallas in 6 (3rd Most likely predicted scenario at 18%)

Brandon Roy and the freaky comeback made the numbers wrong. I’ll take great basketball over any model any day of the week.

Series 4: OKC vs Denver. A coin flip my guess was 55% Denver based on the Altitude.

The Numbers said:Denver in 6

Home Team Win Margin 45%
W4 4%
W5 11%
W6 10%
W7 17%
L4 8%
L5 13%
L6 22%
L7 14%

My Prediction: Denver in 6.

Result: OKC in 5 (5th Most likely predicted scenario at 11%)

I spent hours on this series. I ran every scenario in my head. I thought  Homecourt advantage would be the decider (in Denver’s favor). I forgot about the star system ( stars get calls differently in playoffs see here). That and this little ditty:

What exactly was George Karl Thinking?

To recap:

6-2 for Round #1 for Picking the winners (Arturo and the Numbers)

Numbers got the length right as well for 3 of the series (I only got one). The lessons as always kids, trust the numbers.

Got the coin flip wrong . Missed Orlando not showing up.

Let’s talk round 2 now.

I had:

  1. Chicago over Orlando in 7.
  2. Miami over Boston in 7.
  3. Denver over Memphis in 7.
  4. LA over Dallas in 7.

And  for the rest of playoffs I had Miami over Chicago in 6. Denver over LA in 6 and Miami over Denver in 5.

I obviously need to review these in detail.

First the Numbers for the remaining teams (Note: I had an error on this table initially. Fixed now. Did not affect anything else.):

The really nice part is that now I have the actual minute allocation each team has used for the playoffs. I combine that with the raw productivity (ADJP48 not Wins Produced because having a big as your sixth man? In general better than having a small).

Please note I said :"In General"

With that data, I can do this:

Which is how each team projects based on playoff minute allocation and their ADJP48 numbers.

If I use that to project the matchups I get:

My logic is as follows:

  • Chicago is clearly better than Atlanta but they play down to the level of their competition and are banged up.
  • Miami skews better than Boston when we look at overall but that doesn’t show head to head. This is a coin flip series. If Shaq plays more than 40 minutes and is effective? Throw out that number and prepare for Banner 18.
  • Dallas matches up well with LA. Dallas was also the better team down the stretch. I also don’t trust Bynum’s knees. I go with the average number here.
  • I always felt the winner of OKC-Denver would win Round 2 against Memphis and beat the winner of the battle of the oldsters (LAL-DAL) to go to the Finals. Love Memphis but OKC is clearly better.

Using the numbers I ran the math and this time I’m sticking to it. The math looks like so:

And the 2nd Round Picks are:

Chicago in 4 over Atlanta (Say goodbye to the Hawks!)

This will not happen in the Playoffs

Miami in 7 over Boston (I hope to god I’m wrong here. Or better yet, pray for Shaq over Baby!)

39 sadly is not 29, brah

Dallas over LA in 6 (I could totally see the Mavs getting screwed by the Refs though)

Which of course has never happened before

OKC over Memphis in 7 (Vancouver-Seattle is going to rock!)

Big Country!

For the rest, again just guessing, OKC over Dallas in 6 (Kidd gets abused by Westbrook) , Miami over Chi in 6 (Superstars get the calls, Bosh goes off on Boozer) then Miami over OKC in 7 in what could be an epic first part in a series.

I’m soooo looking forward to the rest of the playoffs.
