Just a question on something I believe to be a rare occurrence. (1 Viewer)

Depends on how you define rare. If you are in a 12-team league, the odds that the points leader and points-against leader would be the same team are 1 in 12. I wouldn't call that rare.I don't think that is right. I took a finite math class in college and we solved problems like this. In actuality it is a 1 in 144 chance (12 teams x 12 teams)
If you're in a league with a guy named Jeff, and ask, "What is the probability that Jeff will lead the league in points scored and points against?" then it's roughly 1/144. But no one's asking that question. If you ask, "What's the probability that the points scored leader and the points against leader will be the same team?" it's 1/12.
Ok, so what are just the simple the chances of a team's ranking matching in both categories? For example being 5th in points and 5th in points against? Or 8th? Or 2nd?
The probability that Jeff will have his ranking matching in both categories is roughly 1/12. The probability that a team (at least one team) in the league will have their rank matching in both categories is ~63%.
And the probability that Jeff will rank precisely 5th in points and 5th in points against is roughly 1/144, which is the specific case that people are getting tripped up on. The original question is general; what are the odds that any team in the league does it? (1/12).
 
OK.. so its pretty hard to determine if something is truly random. Its fairly easy to prove something is NOT random because you only need one example of when its not random. Once its not random, you can throw those stats out the window.

There seems to be 2 camps, the 1:144 camp and the 1:12 camp.

Lets look at the 144 camp first. They're assuming to random events occur with 1:12 frequency. The first is total points, the second is total points against.

Lets assume PPR league scoring

Team A:

QB Aaron Rodgers

RB Adrian Peterson

RB LeSean McCoy

WR Reggie Wayne

WR Andre Johnson

WR Calvin Johnson

TE Antonio Gates

Team B:

QB Tyler Thigpen

RB Shonn Green

RB Ryan Mathews

WR Jordy Nelson

WR Brandon Tate

WR Devin Hester

TE Jeremy Shockey

These teams both have a 1-12 chance of being total pts leader because everything in fantasy football is random? Of course not... so the 1 in 144 example is wrong because the first event doesn't have a frequency of 1-12. I don't know whats right, I'm just pretty sure that 1:144 is wrong.

Lets look at the 1:12 camp

Now, you have a 12 team league with 3 divisions, 13 week schedule. You play everyone in you division twice (6 games) and 7 of the remaining 8 teams. So you have unbalanced schedules, you don't have an equal chance of all outcomes. For example, Team A might not play the highest scoring team at all, while team B plays them twice.

Thats not random (that schedule isnt even random).

Lets look at in on the player level. Right now Aaron Rodgers is one of the highest scoring players in many formats. Its possible that Rodgers can get traded mid-season in a fantasy league and up playing one team A 3 or 4 times and never play against team B.

Do you see what I'm getting at? "Unpredictable" and "random" are two different things...

 
Obviously there is some skill involved. Anyone who drafted team B clearly doesn't have much skill. Team A is pretty much impossible to acquire in redraft leagues.

These are two extremely unrealistic teams in redraft. This alone makes your example very questionable.

The second problem is, that I am specifically referring to the randomness involved in how many points are scored against a team in a season. Assuming a league has divisions randomly decided, and these two ridiculous teams could actually exist, it would be completely randomly unlucky to have team A assigned to your division.

However, there would also be the random chance that you drew team A on a couple of its poorer weeks and therefore very little points were scored against you. When you played team B, they had one of their best weeks, scoring more than either of the times you played against team A.

It is purely random.

One more example. Suppose two teams play the exact same schedule, as far as what teams they play and how many times they play them. However, they don't play the same schedule on a week to week basis.

One of those teams is going to have more points scored against them than the other. Who? Well that would be determined by sheer randomness of which teams you play in which week, and how those teams perform in that given week.

No, I don't see what you're getting at. Ascribing a bunch of events that did or didn't happen, after the fact, and stating that that proves that the probabilities were wrong to start with is completely ridiculous. Of course, you can keep adding as many variables as you want, and each one you add will change the probability. You could do that till the end of time, and never come up with a "true" probability. You're saying that the probability can't be 1/144 because one of the teams will be better than the other? You don't understand probabilities.

I'm willing to assert that fantasy football outcomes follow a normal distribution when large enough populations are sampled.
Exactly.The more samples you take, the more predictable it looks, and patterns emerge.However, any given smaller set of data will have inherent.... randomness, that will cause that smaller sample to deviate from the norm.
 
Whether or not total fantasy points against is truly random isn't really crucial to this problem here. It's sufficiently random that we'll get a good enough approximation. The question is, "What is the probability that the points scored leader will also be the points against leader?"

The 1 in 144 answer is wrong, but not at all for the reasons you're talking about here. It has nothing to do with randomness. 1 in 144 is the answer to a different question, one that isn't interesting and hasn't been asked.

If you want to say that the correct answer isn't exactly 1 in 12 because these things aren't truly random, I think that's a point that many have already made and everyone probably agrees with. But it's close enough. No one's going to be able to quantify it with any more precision than that, at least.

ETA: And just to clarify for those who care about such things, we're getting really sloppy with terms here. Fantasy points are definitely random. What you're questioning is whether or not a team's end-of-year rank in points scored has a uniform distribution. Maybe it doesn't, exactly, but even if it doesn't, it's close enough that we can treat it like it does.

I'll take this a step further. We can all agree that a coin flip is 50/50, right? But yet, if you look at the history of Super Bowl coin flips, heads if favored over tails, I believe. So does that mean it isn't 50/50? Of course not. So I flip the coin. But now we analyze rotation and speed, wind factors, and we see that RIGHT AFTER the flip, the chances are not 50/50. But you can't use hindsight to look back at events to determine what the probability was before the events. That is what your example does. It starts out 1/144, but then you start throwing in other variables: one team sucks, the sucky team plays the best team several times and other teams no times. No sh## things change when you change things.
 
In our league, the guy who had the most Total Points also had the Least Points Against.

Also, he finished 6-7 and almost missed the playoffs.
In the spirit of disagreement that has permeated this thread I am forced to respond that "you are wrong"because the guy who had the most total points in your league also had the FEWEST points against :lmao:

and on the subject of the 1 in 144 vs. 1 in 12, Instinctive's name is accurate because his logic is not...the answer is far closer to 1 in 12 than 1 in 144*

* the reason it isn't exactly 1 in 12 is for the reason others have already cited
Getting tired of this. As stated multiple times, all my analysis was that a SPECIFIC TEAM fit both qualities. That it happens to any team in the league is exactly as Ignatio and CalBear describe.

Not to keep pushing your buttons, but if this is the case, why were you disagreeing with multiple posts that were making that exact point to you earlier?

No buttons :confused:I'm a college student and it was an early morning on dead week after the first night back after winning the Big XII ---> plus I thought the OP was asking for what I gave --> I assumed you were doing what the OP asked as well ---> didn't think to recheck that I had been the one who interpreted OP's question wrong and assumed it was you.Now I've had some sleep after class and I'm back on my game, aka, I actually have reading comprehension now
 
This occurrence is the reason we switched to All-Play, which rewards points and consistency.
Not necessarily. I made it through the FBG Survivor Contest thing to the second leg (was then unable to make a draft) largely on the basis of two weeks at 11-0, in spite of only winning 12 more games, total, in the other 3 weeks iirc.All-Play rewards boom/bust teams just as much as consistent ones. As long as the consistent one if above average consistently, and the boom bust team never goes below 7th-9th or so (12 teams), they'll both be at the top of total standings.

I once scored the least points in the league and was first in points against byh like 300 points and guesswhot I didn't make the playoffs but i di dlearn a lesson about sportsmanship and being a good loser so i chalk itup as a life learning lesson and fee l like i'm a beter person as a result.
