I don't think there is a single "skeleton key" to winning in fantasy football, but if there were, it would be drafting rookies.

It's become increasingly apparent in recent years that rookies are overwhelmingly the best picks on the board, especially as you move into the middle- and late-rounds of drafts.

Best Ball tournaments have specifically illuminated the importance of late-season rookie production with all four Best Ball Mania winners relying on breakout performances from a rookie to help them take down the tournament.

There are a few reasons for this:

As you scroll through the best values I recently identified in ESPN, Yahoo, and Sleeper leagues, you'll immediately recognize that the list is littered with rookies.

But this dynamic creates a conundrum.

If we load up on too many rookies, our teams are liable to get off to a slow start and not make the playoffs.

On the flip side, if we load up on too many veterans, we reduce our chances at nailing rookie and second-year breakouts while also running the risk of our teams petering out at the finish line.

Here are three ways to navigate this dilemma:

Don't Take Too Many Rookies

The issue with taking too many rookies in redraft-managed leagues is that you are likely going to need to cut a bunch of them.

The first few weeks of the waiver wire are the most important of the entire season. We need to be prepared to pounce on the surprise breakout players.

When you draft a rookie for their late-season upside, it can be tough to cut bait so soon. This is an anchoring bias that is hard to shake.

Many of the super late rookie sleepers will end up on waivers anyway, so make sure you are thinking through what kind of role the rookie is likely to have early in the season.

That brings us to our next point…

Prioritize Picks That Offer “Early Information”

I'm not worried about Malik Nabers or Keon Coleman getting off to a fast start. They are going to be on the field and getting opportunities right out of the gate.

But the further down the draft board you go, the less likely we are to get early season production from these rookies.

One of the best ways to analyze whether a rookie sleeper is deserving of a redraft selection is to ask yourself, “What kind of information am I likely to get about their role in Week 1?”

Take rookie RB sleepers Ray Davis and Bucky Irving, for example. I'm high on both of them and want to target them across all formats. Both of them seem to have the No. 2 role locked up on their offenses, but it's still a bit of a mystery as to whether they will have standalone value right out of the gate.

This is the exact spot I want to "take a peek" at on my rosters. Could Rachaad White and James Cook handle 90% of the opportunities and render these guys purely contingent-based handcuffs? Absolutely. But there are also scenarios where these two rookies have forced a timeshare and carved out an immediate role, in which case they will be must-holds on your bench.

On the flip side, some of these rookie WRs (cough: Troy Franklin) are likely buried on the depth chart, no matter how much upside we think they possess. Don't waste roster spots on guys like this that you'll need to churn right away.

While the end of my drafts will still be very rookie-heavy, it will be tilted to the RBs. At WR, I'd rather take a peek at a guy like Jalen Tolbert late in drafts because I think I'll learn more about his role right away.

Build A Strong Foundation

It's a very valuable exercise to work through a draft from back to front, so you know what kind of production you can get late in drafts. This then informs what is optimal to do at the beginning of your draft.

After testing out multiple different strategies for redraft leagues, it became very clear to me that the dominant way to build redraft teams this year is to lock up two bellcow RBs early because the best values later are WRs, and specifically, rookie WRs.

You can see my perfect draft for Yahoo leagues here.

Knowing you can get guys like Nabers in Round 6 and Xavier Worthy in Round 10, means we should focus on getting other positions earlier. Once you have that strong foundation, you can load up on the mispriced rookies. 

I'll admit that I have a very hard time not selecting rookies with all of my late picks, even fully understanding this dynamic.

In a recent high-stakes slow draft where we went full Zero RB, six of our seven RB selections were rookies (Davis, Irving, Jaylen Wright, Audric Estime, Kimani Vidal, and Will Shipley).

The key, though, is that we won't be emotionally attached to any of these fringe guys and will move on quickly if needed. If Estime is buried, he'll be gone and we'll churn for an RB with a better early-season outlook.

The most important thing is to remain flexible after the draft so you don't miss out on any early-season waiver wire gems.
