Sports — C2 (sabermetrics, analytics, ethics)

At B1 and B2 you learned how Americans talk about games — innings, downs, quarters, the points and the bracket. At C1 you handled the cultural weight of US sports: Title IX, the NCAA, the draft, free agency. C2 is the analytics era. Since Moneyball (Lewis, 2003) and the Bill James Baseball Abstracts that preceded it by two decades, sabermetrics has overrun every front office in every major American sport. By 2026, you cannot read The Athletic, FiveThirtyEight, FanGraphs, Baseball Prospectus, Football Outsiders, or Cleaning the Glass without fluency in WAR, expected goals, win shares, true shooting, and Statcast metrics. The C2 vocabulary divides cleanly: the quantitative register of analytics, the bioethical register of doping and concussion, and the institutional-political register of leagues and labor.

The Bill James influence transcends baseball. Football analytics (EPA, success rate, DVOA), basketball analytics (true shooting, defensive RAPM, on/off splits), and soccer analytics (xG, xT, progressive passes) are all conceptual descendants of the sabermetric project: replace folk wisdom with measured outcomes, then audit the measurements. The vocabulary below is what a serious 2026 US sports reader handles without pause.

This lesson assumes you already know the sports themselves. We are after the register — the working vocabulary of the analyst, the GM, the labor reporter, and the medical-ethics writer.

The sabermetric revolution — conceptual frame

• sabermetrics — the empirical analysis of baseball, named for SABR (Society for American Baseball Research). Bill James coined the term in 1980.
• Bill James — the autodidact statistician whose Baseball Abstracts (1977 onward) founded the field.
• Moneyball — Michael Lewis’s 2003 book on the Oakland A’s exploiting market inefficiencies via sabermetric analysis; now a generic term for analytics-driven roster construction.
• the analytics revolution — the broader shift across US sports, c. 2000-2020.
• front office — the management side (GM, scouts, analysts) as opposed to the field/coaches.
• the war room — where draft and trade decisions are made.
• a quant / the analytics department — the data scientists embedded in front offices.
• the eye test — traditional scout-based evaluation; the rhetorical opposite of analytics.
• scout vs stat-head — the old culture war (largely resolved in favor of both).
• market inefficiency — a player or skill the market undervalues.
• regression to the mean — extreme performance tending to drift back to baseline (massively important concept).
• selection bias — the artifact created when sample isn’t random.
• survivorship bias — looking only at the players who made it.
• small-sample-size effects — early-season or short-stint stats don’t predict.
• the eye-popping versus the predictive — the gap between flashy and meaningful stats.

“James’s project was never anti-scouting; it was anti-folklore. He wanted the empirical claim and the eye-test claim to argue in the open, and for the front office to track which one had been right.” — The Atlantic, 2024.

Baseball — the advanced-metrics canon

Baseball is the most analytics-saturated US sport. The 2026 working vocabulary:

Run-value framework

• runs created (RC) — James’s foundational hitter metric.
• wOBA (weighted on-base average) — single number weighting each offensive event by its run value.
• wRC+ — wOBA normalized to league average and park; 100 = average, 150 = 50% above average.
• OPS — on-base plus slugging; a pre-saber holdover that still gets used.
• OPS+ — OPS normalized to league/park; 100 = average.
• ISO (isolated power) — slugging minus batting average; power independent of average.
• BABIP (batting average on balls in play) — diagnoses luck and batted-ball quality.

Pitching

• ERA — earned-run average; classical metric.
• FIP (fielding-independent pitching) — what ERA would be if defense were average.
• xFIP — FIP normalized for home-run rate luck.
• SIERA — skill-interactive ERA; further refinement.
• K/9, BB/9, HR/9, K/BB — rate stats per nine innings.
• whiff rate — percentage of swings that miss.
• CSW% — called strike + whiff %.

Wins and value

• WAR (Wins Above Replacement) — single-number player value over a freely available bench-tier player; the lingua franca of player value.
• bWAR (Baseball-Reference WAR) vs fWAR (FanGraphs WAR) — two computations of the same idea; differ slightly.
• WARP (Baseball Prospectus’s version).
• win shares — James’s earlier framework (3 win shares = 1 win).
• VORP (Value Over Replacement Player) — older predecessor of WAR.
• WPA (Win Probability Added) — leverage-aware in-game contribution.
• RE24 (Run Expectancy 24-state) — run-value contribution by base/out state.
• clutch (FanGraphs) — performance in high-leverage relative to neutral.

Statcast era (since 2015)

• Statcast — MLB’s tracking system (Trackman + Hawk-Eye).
• exit velocity (EV) — how hard the ball leaves the bat.
• launch angle — vertical angle of batted ball.
• barrel — the optimal exit-velocity/launch-angle combination.
• hard-hit % — % of batted balls 95+ mph.
• xBA, xSLG, xwOBA (expected stats) — what the contact “should” have produced.
• sprint speed — straight-line top speed (feet/sec).
• spin rate — rpm on pitches.
• pitch shape — induced vertical and horizontal break.
• arm angle — release-point angle measured by Statcast.
• release point — where the ball leaves the hand.
• pitch tunneling — making different pitches look identical out of the hand.

Defense

• DRS (Defensive Runs Saved).
• UZR (Ultimate Zone Rating).
• OAA (Outs Above Average, Statcast-based).
• DEF (FanGraphs defensive value).
• framing / pitcher framing — catcher’s skill at making borderline pitches look like strikes.
• stolen strikes / lost strikes — framing’s run impact.
• pop time — catcher’s release time to second.
• arm strength — outfielder’s throwing speed.

Pitcher framing — a case study

The discovery that catcher framing was worth 20-30 runs per season (~2-3 wins) for elite catchers — invisible to the eye test, dispositive in the data — became the canonical example of analytics changing player valuation. Jose Molina, a punchless hitter, had a career because his framing was worth more than most regular catchers’ bats. After tracking systems made framing visible to umpires (and to robo-zone training), the gap collapsed.

“Framing is the perfect sabermetric story: a skill nobody could see, then nobody could deny, then nobody could practice.” — The Ringer, 2023.

Basketball — the analytics canon

• PER (Player Efficiency Rating) — John Hollinger’s per-minute metric; first NBA “WAR-like” number.
• win shares — basketball’s adaptation.
• VORP (Value Over Replacement Player) — NBA version too.
• BPM (Box Plus/Minus) — per-100-possessions efficiency vs average.
• RPM (Real Plus/Minus) — adjusted on/off court impact.
• RAPM (Regularized Adjusted Plus/Minus) — Bayesian-shrunk version; the gold standard.
• EPM (Estimated Plus-Minus) — Dunks & Threes; modern composite.
• LEBRON (Luck-adjusted…) — Bball-Index metric.
• DARKO / CARMELO / PIPM — generations of basketball composite metrics.
• true shooting percentage (TS%) — efficiency on all shot types, weighted properly.
• effective field goal % (eFG%) — accounts for the value of the three.
• usage rate — share of team possessions used while on court.
• on/off splits — team performance with player on vs off the court.
• net rating — points scored minus allowed per 100 possessions.
• pace — possessions per 48 minutes.
• the heliocentric offense — one star creates everything (Luka, Harden-era).
• 5-out — five players spaced beyond the arc; modern spacing orthodoxy.
• drop coverage vs switch vs ice vs hedge — pick-and-roll defensive schemes.

“Cleaning the Glass strips out garbage time and reports the part of the game that actually counts, and in doing so it gave us, for the first time, an honest look at second-unit lineups.” — Hollinger, on Cleaning the Glass, 2022.

Football — the analytics canon

• EPA (Expected Points Added) — the football equivalent of WPA.
• success rate — % of plays that achieve enough yardage for the down/distance.

• xPoints — implied table position from xG.
• possession-adjusted defensive stats — corrects for the fact that more defensive actions come from less possession.

Doping — the bioethical register

The vocabulary of WADA, USADA, BALCO, Lance Armstrong, and the Russian state-doping affair.

• PED (performance-enhancing drugs) — umbrella term.
• anabolic steroid — testosterone-derivative muscle-builder (Winstrol, Anadrol, the Designer Steroid era).
• HGH (human growth hormone) — protein hormone for tissue growth.
• EPO (erythropoietin) — boosts red-blood-cell count; the cycling-doping drug par excellence.

“The strict-liability standard is the doping regime’s bargain: it sacrifices the principle of mens rea in exchange for enforceability. An athlete who claims contaminated supplements faces the same suspension as one who deliberately doped.” — Sports Illustrated, 2021.

The concussion crisis — vocabulary

The 2010s-2020s reckoning with traumatic brain injury, especially in NFL but also NHL, soccer, and combat sports.

• concussion — mild traumatic brain injury (mTBI).

• targeting — NCAA football rule criminalizing helmet-to-head hits.
• the helmet of the future — protective-equipment debates; the limits of equipment.

“The Mike Webster case redefined the obligations sports leagues owe to their workforce: not just to compensate injury, but to disclose risk. By 2016 the NFL had a $1 billion settlement and a generation of fans who could no longer claim ignorance.” — The Atlantic, retrospective 2024.

Common Russian-speaker mistakes

1. *Football* meaning soccer when speaking AmE. Russians follow international usage and mean soccer. In US contexts, football is American football; soccer is what the rest of the world calls football. He plays football for Real Madrid will be heard as American football in the US — confusion guaranteed. Use soccer in any US-set conversation.
2. *Sportsman* for athlete. In AmE, athlete is the unmarked word for any competitor. Sportsman survives narrowly (hunting/fishing contexts: outdoorsman, sportsman’s club) but sounds dated/British when used for a basketball or football player. Russian спортсмен maps to athlete.
3. *Make sport* / *do sport* as a hobby description. Calques. AmE says play sports, work out, train, play {basketball, etc.}. I do sport on weekends sounds non-native; native is I play sports or, more often, I work out / I play basketball.
4. *Score* misused as verb for individual players in all sports. Russians often say he scored generically. AmE has sport-specific verbs: score (a goal) in soccer/hockey, make a basket / hit a three in basketball, score a touchdown in football. Saying he scored in a basketball context sounds odd if used standalone; native English specifies the unit.
5. *The result is 3:2* for a final score. Calque. AmE uses the final score was 3-2 (dash, not colon), or simply 3-to-2. The result was three to two is fine in narrative; the result was three colon two is impossible.
6. *Champion* as adjective. Russian чемпион is used adjectivally (champion team). AmE says championship team (the team that won the title) or the defending champions (currently holding). The champion team sounds wrong; the championship team or the champions is right.
7. *Sportive* for athletic. False friend pattern. Sportive is a rare English word (archaic, “playful”). For “athletic” / “sporty” use athletic (as adjective for performance) or sporty (informal, for clothing or cars). He has a sportive build is wrong; he has an athletic build is right.
