Roberts reads Bill Belichick as a coach acutely aware of his own limitations. Despite immense statistical data on every college player, none of it reliably predicts success once a player enters Belichick's demanding system, so his true hit rate is small. His response is to enlarge the denominator: trade higher-rated picks for multiple lower-round selections, giving himself more shots. He then tests players in preseason — the real crucible — and cuts ruthlessly on merit, ignoring the sunk cost of a pick's rank. The strategy explains famous finds like sixth-round Tom Brady and undrafted signings who made the team, alongside a willingness to release highly-drafted players who simply weren't good.
Origin
Extracted from Russ Roberts' discussion of Bill Belichick on Modern Wisdom with Chris Williamson. Roberts notes Belichick studied economics at Wesleyan and understands trade-offs unusually well.
Core principles
- 01Even with abundant data, predicting how a person performs in your system is genuinely hard
- 02When your hit rate is low, the reliable lever is more attempts, not better guesses
- 03True ability only reveals itself in the actual crucible, not in the measurables
- 04Ignore the rank you paid for a pick — judge only the player in front of you
- 05Trade prestige for volume of shots on goal
How to run it
- 1
Admit the low hit rate
Accept that even with speed, strength, and yards data, you cannot know how a player will perform until they are in your specific system and under pressure.
Pro tip Self-awareness about your own limits is the foundation, not a weakness.
- 2
Enlarge the denominator
Since you expect only about one good player per round, give yourself more chances by acquiring more selections.
- 3
Trade prestige for volume
Trade higher-rated first, second, or third-round picks for multiple picks in later rounds, converting a few expensive bets into many cheaper shots.
- 4
Test in the crucible
Discover who is actually good by putting candidates through real conditions — preseason — rather than trusting the measurables.
Pro tip The 'vampire game' is the only place hidden ability becomes visible.
- 5
Cut on merit, ignore sunk cost
Release a highly-drafted player if they aren't good, and keep a late-round or undrafted player who is. Do not protect a pick to avoid looking wrong.
Watch out Refusing to cut a high pick to save face is the sunk-cost trap this whole method avoids.
In the wild
Belichick is famous for finding excellent players in late rounds — Tom Brady being the archetype — and for signing players who went entirely undrafted, adding them after the selection process was over. The large denominator plus real-conditions testing surfaces value the ranking system missed.
→ A steady supply of high performers from low-cost slots, most famously a sixth-round quarterback who became a legend.
Belichick will release a player he drafted high once he concludes they aren't good, rather than clinging to the pick to avoid admitting a wasted selection. He judges the player, not the price he paid to acquire them.
→ Sunk-cost blindness is removed from roster decisions, keeping the team on merit.
Common mistakes
Over-trusting the measurables
Treating combine and statistical data as predictive ignores that fit and performance only emerge inside your system under real pressure.
Protecting a bad high pick to save face
Keeping an underperforming player because they were drafted high is the sunk-cost fallacy that quietly weakens the roster.
Is it for you?
Best for
Coaches, managers, and recruiters selecting talent under high uncertainty where fit only shows up in practice.
Not ideal for
Settings where each selection is extremely expensive or where candidates cannot be tested before commitment.
From the transcript
“he's realized that his success ratio is small so his best bet is just have a large denominator pick a lot of players”
“he's also famous for cutting people that he thought were really good that weren't he doesn't go oh I'm going to look stupid I wasted…”
