A real gem from the comments at Advanced NFL Stats (which has actually been repeated several times over there):

Quote:
While the numbers may be accurate (granted they are league averages being generally applied here), the interpretation is incorrect. The 0.79 WP, describes the total probability that the Patriots would win PRIOR to running a play. Once the decision is made to "go for it", the function bifurcates to two independent probabilties - (1) a 60% probability of winning based on successful conversion; given the assumption that a first down would win the game -which I'll concede, and (2) a 47% probability if the conversion fails. Thus, the correct interpretive reasoning is "if we go for it, we have a 60% chance of winning now based on conversion, and would still have a 47% chance of winning even of the conversion fails". If instead the decision is made to punt, the probability of winning is 70%. The reality is that punting would have given the greatest probability of winning.
The guy used the word "bifurcate", so he must be right.

That's Jackson saying "you play the odds and punt" but with a bunch of $20 words thrown in.

Nit: if blocks cancel out, they might have to try a longer fg... or they might accidentally score a TD and Pats get the ball back...

But yeah, you're pretty much right.

He is basically saying they have three options:
go for it and succeed (.6WP)
go for it and get stopped (.47WP)
and punt (.7WP)
Since punt is highest they should chose punt.

IE you can't combine the odds of making it and winning and getting stopped and winning because those are two different events, or possibilities, or something. I really don't know. But he appears to be comparing those three percentages and choosing punt because its the biggest of the three.

edit: and why the fact that it is Peyton Manning of all people only makes it an even more correct play.
honestly man, i gots respect for ya. glad to see ya come around. pls try to apply it to further decisions

No, he's somehow looking at the % of the time you win outright if you go for it and make it, but not adding the % of time you still win even if you don't make it.

So if you go for it you make it and win outright 60% of the time. But the other 40% of the time that you go for it and don't make it, you still win 47% of the that.

So you add 60% to (40%*47%) = 78.9% (using his numbers).

It's just like deciding whether or not to shove in a SNG. Some of the time they fold and you take the blinds uncontested. Some of the time they call and you're still 40% vs. their range.

It's just math. There is no argument against it - 'bifurcate' notwithstanding.

No I dont agree with his call, give Peyton 29 v at least 60 yards and yes he screwed me because I had a big play on the Pats ML

i mean he's saying that it's 60%+(.4*47%) right there. baffling.

lol my brother's roommate is like I don't believe math and sports mix...it's not how u play the game. He thinks that the guy on advanced statistics fudged his numbers somehow.

I don't think u can really explain this stuff to most sports fans...its like trying to argue there is no god to a religious person.

wilbon largely is an idiot. he proves it every time he opens his mouth. I like Wilbon, he's good at reporting stories, and PTI is awesome because of the chemistry, but Wilbon's never been good at analysis

So where did they do the stats analysis on ESPN - was it sportscenter, or monday night countdown? Were mike and mike presenting it?

i forgot who posted it, shipit I think, but he was right. Just dont' watch. I never watch this crap. The only highlights/analysis show I watch on TV is NBATV's gametime, cuz it's usually pretty awesome unless Cheryl Miller is involved.

The only mainstream sports media I consume is the occasional PTI and Simmons.

you kinda butchered this, since you completely ignored the other side (playing for a tie). You don't do it because you come up with 15 more often than 12.

You do it because you win more than you lose. A lot of that has to do with OT being basically a coinflip.

fwiw I'm not sure how clear this decision is for all team matchups. Bad O vs good D might shift it to kicking the point. I haven't seen the calcs or tried to calculate them myself.

OMFG Dilfer on espn right now...After having a full day to soak it in it angers him to even hear the other side of the argument.

He said you just can't trust BB to make calculated decisions anymore...

LOL OMG DILFER DIE DIE DIE DIE

I am just getting tired of the "You play the percentages" argument from people that say you should punt there. THE PERCENTAGES SAY YOU GO FOR IT!!!!! I just want to stop them and ask them to explain the "percentages."

Didn't he agree with him? Millen said "you play the percentages" and probably punt there so isn't that in agreement with what Dilfer has been saying?

It gets interesting though with say Colts/Pats offense vs. an average or worse defense. If you can get anywhere above .5 you should be going for 2 most of the time right?

No, it's because the chances of getting it once are higher than missing it twice.

Miss 60% of the time, so missing twice is .6 x .6 = .36, so if you get it more than 36% of the time its plus ev and almost every nfl team does.

no, he's saying:

chances of scoring 15 points: .4*.99 = .396
chances of scoring 12 points: .6*.6 = .36
chances of scoring 14 points: 1-.396-.36 = .244 (or .6*.4=.24)
