NFL DFS Late Swap Case Study: Inside A $100K Milly Maker Run
Most NFL DFS strategy content stops at lock. This is an NFL DFS late swap case study about what happens after it, told through one of the most detailed real examples we've published: high-volume DFS player Justin Freeman, better known as HeavyChevyJF on DraftKings and FanDuel, sat down with host Neil Warfield on High Stakes (the show ran on our channel under the Awesemo name, before the Stokastic rebrand) and walked through how he managed a 150-entry Milly Maker set across the four-game NFL Divisional Round weekend of January 2021, climbing all the way to 3rd in the tournament and a $100K payday.
We're using an older slate on purpose. Four sequential kickoffs across two days is the cleanest laboratory late swap ever gets, and the roster names have aged while the framework hasn't. The engine behind the whole story is one line Freeman delivers as settled fact: the field does not swap as often as it needs to in large-field tournaments. Everything else flows from that one exploitable habit: the lineup tiers, the winning-score math, and the swap sequence that carried a lineup to third. By the end of this piece you'll know the three-tier triage framework he described, and you'll see the Travis Kelce decision that made the run possible.
The Quick Answer
On slates with time between kickoffs, late swap in practice means re-sorting your live lineups into three tiers as games come off the board: lineups with a real path to winning, lineups dead to first but alive for a big prize, and lineups fighting for the cash line. On a four-game January 2021 playoff slate, Freeman played chalk with his live-to-first lineups, went aggressive with the middle tier, and one Alvin Kamara-to-Travis Kelce swap helped carry a lineup to 3rd in the Milly Maker, 0.04 fantasy points behind second and 3.6 off the million. The full triage framework, the winning-score math, and the $100K decision itself are below.

The Setup: Four Playoff Games, 150 Lineups, And Time To Think
The slate that produced this story was unusual in the best way: the NFL Divisional Round of January 2021, four games spread across two days, each kicking off one after another with roughly an hour and a half between them, plus a full overnight between Saturday and Sunday. Freeman normally avoided 150-max entries on classic NFL slates because the portfolio was too big to manage well. This weekend was different: a short slate, sequential kickoffs, and real time to think between every game. If short-slate structure is new to you, our Milly Maker strategy guide covers how large-field GPPs change lineup building in the first place.
That structure is what made his edge usable. Freeman's core belief, stated flatly in the interview, is that the field does not swap as often as it needs to in large-field tournaments. Too many entrants set their lineups, watch, and hope. Every window that passes without the field re-deciding its open roster spots is equity left on the table for the player who does. Hold that thought, because the swaps that carry this story only work against a field that under-swaps.
The sequential schedule turned late swap from a scramble into a project. He recorded his decision process on video mid-slate, sorting every live lineup by what it could still accomplish. That sorting step is the framework worth stealing.
The Three-Tier Triage: Sort Every Lineup By What It Can Still Win
With two games played and two remaining, a 150-entry portfolio isn't one decision. It's 150 lineups with different amounts of scoring left, different salary structures, and different places on the leaderboard. Freeman's move was to stop thinking about lineups individually and start thinking in tiers. Every lineup got assigned an objective, because as he put it, every lineup may have a different objective.
| Tier | Leaderboard Reality | The Right Move |
|---|---|---|
| Live To Win | A real path to first place | Reverse course and play chalk; protect the position |
| Dead To First, Live For A Big Prize | Cannot win, but a serious payout is still reachable | Get aggressive; swap toward low-owned, high-ceiling pieces |
| Fighting The Cash Line | Only min-cash equity remains | The lowest priority; Freeman mostly left these alone |
The counterintuitive row is the first one, and it's the row I keep coming back to, because it's the one most players get backwards. Freeman had roughly seven lineups that were crushing, likely built around a highly leveraged player who had already smashed. His instinct wasn't to press. It was the opposite: those lineups no longer needed leverage, because the leverage had already paid. In his words, he was the one in the driver's seat now, so those lineups went toward chalk in the remaining games. Meanwhile the roughly 30 lineups a tier down, technically dead to first but alive for a serious payout, were the ones that earned the off-the-wall swaps. Leverage is a tool for catching the field, and how leverage actually works in NFL DFS is worth internalizing before you ever apply this tier logic, because the whole framework is just leverage turned on and off per lineup.
Once every lineup has a tier, you still need to know what score you're chasing. That's a math problem, and Freeman treats it like one.
A Worked Example: Project The Winning Score, Then Work Backward
Freeman's mid-slate process starts with a simple anchor: find the best lineup on the leaderboard with zero player minutes remaining. That score is locked. Nothing can change it, which makes it a hard floor for what first place will require. From there he projects what the winning score will actually become, then walks each of his live lineups backward: how many points does this lineup need from its remaining players, and how much leverage does it need to get there?
The leverage half of that question is where his thinking gets sharp. A player at 15% to 20% ownership feels like chalk under a countdown clock, but Freeman flips it: that still means 85% of the field doesn't have him. Is that enough separation to climb from where this lineup sits? Sometimes mediocre chalk is plenty. Sometimes a lineup buried on the leaderboard needs a piece so thin the field won't even consider it.
He told a story from a 2022 spring-league slate that shows the principle with the results stripped away. He swapped off a chalky piece onto a receiver at 0.2% ownership, a player he knew would be one of only five active receivers on his team that day. The two players scored nearly the same, and the swap probably cost him three or four points across the board. He still called it absolutely the right decision, and he's correct: a near-identical projection at a fraction of the ownership is exactly the trade the middle tier exists to make. Process over results is easy to say and hard to live when the points come in flat. The same math, with the results finally attached, is what produced the $100K run.
The $100K Decision: Kamara Off, Kelce In
Back to the playoff slate. Two games done, two to go, and Freeman's climbing lineups faced the decision that would define the sweat. He swapped off Alvin Kamara and onto Travis Kelce, which turned the lineup into a Patrick Mahomes, Darrel Williams, Tyreek Hill, Travis Kelce core and left enough salary to consider adding Byron Pringle over the Cameron Brate piece already in the build.
That Pringle-or-Brate call is a beautiful little late-swap exam. The case for Pringle: he correlates directly with Mahomes, and stacking a quarterback with his pass catchers is the backbone of GPP construction. The case for Brate, at least as host Neil Warfield read the decision: the lineup already had four players tied to the same offense, and piling on a fifth meant every egg in one game script. The build stayed on Brate. Pringle finished with two catches for 14 yards. Brate put up nine fantasy points. Whatever the exact reasoning, staying put paid off, and this story ends with margins thin enough that it mattered.
That Brate lineup climbed all the way to 3rd in the Milly Maker, a tournament Freeman estimated at a couple hundred thousand entries. The final margins were brutal: he finished four hundredths of a fantasy point behind second, and 3.6 points behind first and the million. One more Leonard Fournette rushing yard would have meant second place outright. And the cruelest what-if of all was already on the field: Mahomes, carrying a questionable tag, left the game injured in the second half with 21.6 fantasy points banked while Chad Henne finished the drive work. Hill scored 22.9. Darrel Williams, at just 2% ownership, added 13.4. A healthy Mahomes probably wins Freeman the milly. Instead he "settled" for $100K, watching the final minutes on a group video call with friends he had cut into the entry, everyone trying not to spoil the feed for whoever's TV ran a few seconds behind.
Remember the habit this whole article hangs on. Freeman's $100K didn't come from a perfect Sunday-morning build. It came from being one of the few entrants still making decisions after lock, with a framework for which decisions each lineup deserved.
Running The Same Process With Sims Instead Of A Notepad
Everything Freeman did by hand maps onto numbers you can actually pull. Worth saying plainly: Freeman runs his own DFS simulation product, so his optimal-rate framing is vendor-neutral expertise, not a plug for ours. His rule of thumb from the interview: if a quarterback is optimal in 30% of simulations and only 20% owned, you should be heavy on him. That optimal-rate-versus-ownership read is common to any credible simulation approach, and it's the same comparison Stokastic's NFL DFS Sims are built around: when you're weighing a swap, put a player's chance to matter next to his ownership before you commit. You can try the Sims free and run that comparison on any slate. The same late-breaking news that powers these swaps moves pick'em boards too, and Stokastic Prop Tools (PrizePicks + Underdog projections) point the identical volume-and-news reads at player props.

The Mechanic To Steal This Sunday
The piece of this I'd steal first isn't the sweat, it's the anchor. Next time you have live lineups after an early window, open the leaderboard and find the best score with zero player minutes remaining. That number is your floor for what winning takes. If the locked leader sits at 140 and you project the eventual winner lands near 165, a lineup needing 60 points from two remaining players isn't live to first, no matter how good it looks; it's a middle-tier lineup, and it's earned an off-the-wall swing, not a chalk hold. Sort every entry that way, give each tier its objective, and make the swaps the tier calls for. One $100K finish doesn't validate a framework by itself; the reason to steal this process is that the logic holds whether or not the points show up that day. The field will still be watching its Sunday-morning lineups like television. You'll be the one still playing.
Frequently Asked Questions
What is late swap in NFL DFS?
Late swap is the ability on DraftKings and FanDuel to edit any player in your lineup whose game has not yet kicked off, even after the slate locks. Our NFL DFS late swap guide covers the site-by-site mechanics in full.
How much time do you actually need to triage a big lineup set?
More than a normal Sunday gives you. Freeman normally skipped 150-max on classic NFL slates because the portfolio was too big to manage; he only ran this playbook on a playoff slate with roughly an hour and a half between kickoffs plus an overnight break. On tighter slates, triage fewer lineups or pre-plan your pivots before lock.
Should winning lineups swap toward chalk or leverage?
Toward chalk. A lineup with a real path to first has already banked its leverage, so the job shifts from catching the field to protecting position. Leverage is for the lineups that still need to climb, which is why the middle tier gets the low-owned swings.
When does late swap not apply?
When there's nothing left to swap: single-game showdown slates and any slate where every game kicks off at once lock your full roster immediately. The edge only exists on multi-window slates where some of your players start later than others.
