When Should You Pick a Popular Team In A Survivor Pool?
Sometimes, we recommend taking a popular favorite, and other teams we avoid them. Here are some reasons that could be the case.

One of the questions we get all the time is why we are recommending (or not recommending) a particular very popular team.
Subscribers may see situations that look roughly similar on the surface, but where the recommended strategy is different. For example, maybe early in the season we recommended avoiding a big favorite who was the most popular choice. But now are recommending choosing a later week’s most popular team.
The answer in most cases is simply that not everything about the situations is the same. All of the following could be factors:
- The specific win odds;
- The specific pick popularity;
- The distribution of win odds and pick popularity of other potential choices that week, which can alter the EVs of the team in question;
- The Future Value of the team in question, relative to other options.
- The specific pool size and rules.
Let’s go through some examples that might illuminate those things better.
A Tale of Two Big Favorites
In Week 3 of 2018, the Minnesota Vikings, the most popular choice, were favored by 16.5 points over the Buffalo Bills. In Week 4 of 2019, the Los Angeles Chargers, the most popular choice, were favored by 15 points over the Miami Dolphins. Both were the most popular public pick of the week, at over 40%. Our recommendations largely avoided Minnesota in Week 3 in 2018, but were heavily on the Chargers in Week 4 of 2019.
Because little differences add up. Let’s look at those differences to see how expected value is dynamic and depends on multiple factors.
Pick Popularity Differences Add Up
The biggest difference between these two cases was in pick popularity. And not only the pick popularity of those two top favorites, but also the relative differences compared to the second-best options by win odds.
In both weeks, the teams with the next highest win odds were at roughly the same level. Jacksonville in 2018 and the Los Angeles Rams in 2019 were both favored by about 9.5 points. But the pick distribution of the top two options was very different.
- Week 3 of 2018: Minnesota was picked by 58% of entries, Jacksonville by 10%.
- Week 4 of 2019: Chargers were picked by 44% of entries, Rams by 29%
In one case, the largest favorite was being picked nearly six times as frequently; in the other less than twice as often. Because of those relative differences, the Minnesota pick had a lower expected value. You could “fade” Minnesota by taking some somewhat riskier, but unpopular choices, and if the Vikings lost, a larger chunk of the pool would be wiped out.
Meanwhile, the Chargers-Rams scenario actually produced the opposite effect. Because the relative pick popularity difference between the two was not as large, you could instead “fade” the Rams by still taking the safest option, which is the direction most of our recommendations went that week.
Add in that Minnesota had more future value in 2018 entering Week 3 than the Chargers did in 2019 entering Week 4, and the expected value of the two picks was different enough to alter the recommendations, even though they looked like similar cases on the surface.
Examples from the 2022 Season
In 2022, there were nine weeks where a team had a pick popularity of at least 30%.
We ended up recommending our users actually take one of them at a higher rate than the public (Dallas in Week 8 vs. Chicago).
In three cases, we recommended the popular pick at a rate lower than the public, but across all pool types were reasonably similar (within 10% of the public). Those were:
- LA Rams (Week 6)
- Baltimore (Week 11)
- Jacksonville (Week 18)
In the five other cases, though, we recommended the popular team well below the public, in some cases barely recommending them across all pool types and portfolio sizes. Those were:
- Green Bay (Week 4)
- Buffalo (Week 5)
- New York Giants (Week 10)
- Miami (Week 12)
- Cleveland (Week 13)
Let’s go through the differences to illustrate why recommendations either tended toward the very popular public choice or away from it.
Future Value Matters
Future Value can play a role in why one popular team is recommended. We recommended Green Bay and Buffalo at much lower rates earlier in the season, in part because of the Future Value each had, in particular Buffalo. The Bills had the highest future value entering Week 5. While they wouldn’t be favored by 14 again, they were favored by a touchdown or more in eight different weeks in the future. And because of the high popularity in Week 5, they would be far less popular in those future weeks and have a good EV.
Of course, this has a limit, and it’s not the most important factor in most cases. Those later popular choices (New York, Miami, and Cleveland) had low Future Value, which was a factor in why the public was so heavily using them. But we’ll get to them soon.
It’s easy to look at the popularity numbers and just lump them together as “very popular.” But Miami was at almost 60% popularity, while Dallas was at 31%. The best choices are dictated by the specific numbers, and higher popularity lowers Expected Value. If Miami had been just a little less popular, they would have likely moved up as a more frequent recommendation. Similarly, if Dallas had seen their popularity numbers rise well above 40%, the attractiveness would have been reduced.
Win Odds Definitely Matter
Finally, win odds play a big role in which popular choices still remain fairly priced, and which have become overvalued. Just because two teams have the safest win odds in two different weeks doesn’t mean they are the same.
And the way win odds affects the impact of high popularity may not be intuitively obvious. Pick popularity is most important as a measure of how many opponents could be eliminated with a loss, giving you an incentive to avoid picking a team. That “with a loss” part is key. The higher a team’s win odds are, the less likely you will gain any ground by avoiding them. There is a vast difference, for example, between avoiding a 90% favorite and an 80% favorite. Your opponents are twice as likely to lose by picking the latter, which makes a high pick rate twice as important.
When we were way under the public on picking the Giants in Week 10, for example, the Giants having only 68% win odds was a big factor. Avoiding them had a reasonably high payoff rate. Baltimore, on the other hand, was at 84% a few weeks later as a popular pick.
The Other Options Matter
What else is available, and what the outlook is for each team, is also a differentiator. When we were more similar to the public in Week 6 on taking the Rams, one notable factor was that Tampa Bay had similar popularity, just below 30%, and more future value. So a pick on the Rams in that case was a preference on the Rams’ combination of lower future value and EV relative to a pick like Tampa Bay.
Every Week is Different
The ultimate answer to when you should and should not take the most popular choice, then, is — it depends. Win Odds, Popularity, and Future Value all matter. Subtle changes to each can make a difference.
Every large favorite is potentially a good choice … or a poor one … depending on where the numbers end up.
That’s why we built the Survivor Picks product, to break down all those factors and do all the heavy lifting and analysis in order to make the best choices.
