It's stuff like this which shows why Bill Belichick is truly ahead of the game.

He cited some stats that started him on this trend, and over the years he punted fewer and fewer times. Last year he said he punted only 3 times. . He also stated that he onside kicked more than half the time and had 7 different onside kick plays. Like punting he believes that the risk is worth the reward.

IIRC it was on the show that follows Mike and Mike.

BTW- the most interesting part of that article that was linked was the fact the BB responded to the guy who wrote the paper. He told him he should also consider the emotional factor of the team if they FAIL to pick it up. What was even MORE interesting was that the professor redid his numbers with that in mind.....and found out that it STILL didn't matter. Teams punt too often.

It's a fantastic statistic.

The best quote there is that "he onside kicked more than half the time and had 7 different onside kick plays." How many onside kick plays do NFL teams have - maybe 3 at the most? Perhaps if a bit more thought was put into successful onside kicks, they could get a success rate better than 20%.

It's impressive that Belichick would read a paper, but he supposedly has intellectual curiosity about all sorts of non-football topics.

I saw the theory in control systems, but the bottom line still comes down to modeling the problem. It isn't just plugging in numbers. You have to identify what is relevant to determining an outcome. As that paper notes, much of the data is based on third down and is used to establish a model for fourth down planning. The data is also based on 1st quarter decisions, not 4th quarter and finally assumes the coach is risk-neutral, not risk-seeking or risk-averse. A basic understanding of football would probably tell you these are fairly major assumptions in professional football. I suspect based on these assumptions, Belichick is probably not employing the paper's theory but rather his own knowledge of teams' tendencies, his tendencies and basic probability.

If you are having trouble falling asleep, most of the theory and equations can be found here.

So Belichick gets it and Mangini doesn't.

Pretty much...

It's that type of thinking that allows smart people to get ahead? Give me a break. One of these wonderful situations could be presented. Let's just use Albert Haynesworth and the Pats O-line. Going into a game against the Redskins, your Economic/Mathematics genius in the building tells you that you have an 80% chance of being successful on a qb sneak within the 20 yd line against Haynesworth.

You're thinking, "It's 4th and 1, and we are on the 20 yd line with the game on the line, our local genius said we have an 80% chance of success." Your gut is telling you "Hey dumbass! Haynesworth has 4 TFL on the game and has been owning every hat we put on 'em!"

You gonna go for it because the odds are in your favor or are you going to be realistic and understand that those 4th and 1 statistics gathered prior to the game have no impact on the current game you are involved with?

If that example wasn't a good one, I apologize. I'm sure some of you are smart enough to get what I was saying.

All that matters in this game is reaction speed, and execution. You take care of both of those things over the course of a football game, and do so with more consistency then the team you are facing, I'm gonna bet you win the game.

Having good information on what is more likely to work in certain situations that other teams don't pay attention to can make a huge difference over the course of the season if applied and executed well. Take two teams with similar execution and give one the advantage of superior understanding of what is more likely to be effective and what team do you think wins? What team do you think has a better chance of winning the super bowl? Leave no useful stone unturned. (Also, better statisticians are pretty much the main reason for the resurgence of the Red Sox. Different game, but understanding your sport better makes your organization better.)

Isn't this simply called film study? Like I said on my first post on the subject. I find it interesting, but not at all game breaking. If this is what our team is focusing on then maybe they need to throw the books away and have the coaches focus on making appropriate adjustments after half time. I'm sure it wasn't math and statistics that allowed Josh McD to see that we were giving his receivers a 45 yd. cusion.

No. One is micro and the other is macro.

I'm pretty sure they have guys do research and report interesting findings to the coaching staff so that the y can evaluate the usefulness.

That's apples and oranges, though. There's no reason the two can't work in concert.

The article is very interesting though.

I think you're going WAY too far in the other direction. What you've said renders play selection meaningless -- might as well run it up the middle on 3rd and 15 if all that matters in this game is reaction speed, and execution.

Absolutely every NFL coach relies on "averages" to make decisions. That's why they're passing on 3rd and long, punting rather than attempting 70-yard field goals, etc. What's unusual about Belichick is his willingness to reconsider longtime conventional football wisdom when data point him in a different direction.

The studies described in that article do NOT tell you what the right move is in a particular real-world game situation, given the myriad variables of personnel, field, etc. They DO suggest that coaches should adjust how they make those decisions to avoid common biases in judgment. E.g., the fact that overall, NFL teams punt and go for 2-point conversions too often shows that the current conventional wisdom is flawed. A competitive advantage can be gained by fixing those flaws, and Adams & Belichick will be out in front trying to grab that advantage.

Probably the clearest example of this is in the part about the draft and "hyperbolic discounting." We all know that the Pats trade picks into the future to improve positioning more than any team we've ever seen. They're systematically taking advantage of the established "1 round up" for a future pick -- which for teams with stable management is simply an irrationality in the market. It's basic draft pick arbitrage.
