Tennessee has always been three different places, economically and culturally. I wanted to know whether that shows up in high school soccer.
The three grand divisions are separated by the Cumberland Plateau to the east and the Tennessee River to the west, boundaries recognized in state law since 1796.1 They developed distinct economic identities over the two centuries that followed, and that divergence is visible in the ZIP code socioeconomic data from The Zip Code Effect. By looking at the cross-regional competitive record, we can better understand which regions are actually dominant on the field and where the economic framework stops predicting the outcome.
East Tennessee's mountain communities voted against secession in 1861 and spent the Civil War as contested territory, which left a cultural imprint that still holds. The region built its economy around manufacturing, coal, and small agriculture rather than plantation systems, and it kept a political identity distinct from the rest of the state well into the 20th century.1 Middle Tennessee grew around Nashville, which served as the state capital from 1812 onward and compounded that institutional advantage over time. Nashville's emergence as a music industry center from the 1950s forward, combined with post-WWII suburban expansion, made Williamson and Rutherford counties some of the wealthiest in the South. No one in Tennessee would debate that Nashville is the most economically advantaged of the three regions. West Tennessee's center of gravity has always been Memphis, which developed as a Mississippi River port city with deep economic and cultural ties to the Delta rather than to the rest of Tennessee. Memphis's post-industrial economic decline since the 1970s is well documented, and the disenfranchisement of its predominantly Black urban core from institutional investment reflects regional and national inequities that show up directly in the neighborhood wealth data.
In the Socioeconomic Index scores,2 Middle Tennessee programs average 66.2, East Tennessee programs average 50.6, and West Tennessee programs average 39.3. None of those numbers would surprise anyone who lives in the state. Based on Part I's regression, that 27-point spread should produce a measurable competitive advantage for Middle on the field. The cross-regional record says otherwise.
One thing visible on the map without any analysis: the school density matches Tennessee's population density almost exactly. Memphis clusters tightly in Shelby County and spreads into the first-ring suburbs. Nashville fills Davidson and the Williamson/Rutherford/Sumner corridor. East Tennessee is different. Knoxville is a dense cluster, Chattanooga is a second dense cluster, and the Tri-Cities form a third, with long stretches of sparse coverage between all three. That structure is part of what makes East Tennessee a different competitive ecosystem than the other two regions. Nashville's 88 programs are mostly within 40 miles of each other. East Tennessee's programs are spread across a 200-mile corridor with three separate metro anchors.
A cross-regional matchup is any game where one team's home county is in a different grand division from its opponent's. The dataset has 4,745 such games with complete region data: 2,391 boys, 2,354 girls. East-Middle games dominate the sample at 2,801 because proximity and shared invitational circuits make those matchups common. East-West (659 games) and Middle-West (1,285) happen mostly at neutral-site tournaments and at the state championship, where TSSAA stages all classification brackets at Murfreesboro regardless of where teams travel from.3
Switch to boys state cup only and East's win rate against Middle climbs from 53.8 percent to 68.2 percent, 36 wins in 55 state tournament matchups. That is the most dominant cross-regional result in the dataset. In girls, the state cup tells a completely different story: West Tennessee wins 72.2 percent of state tournament games against Middle, 19 wins in 27 games, despite the largest SEI gap of any regional pairing.
The combined record also contains a finding the boys-only view hides. West Tennessee beats Middle Tennessee overall in the combined record, 53.5 percent, including a 65 percent girls win rate. The wealth gap between those two regions is the widest in the dataset. The competitive record runs the other way.
The SEI model predicts East should lose to Middle. The neighborhood wealth gap translates to a predicted 44.1 percent win rate for East boys. The actual rate is 53.8 percent. That 9.7-point swing is larger than the SEI effect size across any single quintile in Part I. East is not just outperforming expectations. It is reversing a predicted deficit by a margin bigger than the model's own precision.
Middle's relationship with West is the second number worth sitting with. The model predicts 60 percent for Middle boys against West. They actually win 51.8 percent, and for girls West wins 65 percent. West Tennessee's cross-regional record is driven heavily by Memphis Metro programs (Collierville, Houston, Germantown, Christian Brothers) whose individual SEI scores sit above 80, well above the regional average of 39.3. The average undersells what actually shows up in cross-regional games because the rural West TN schools that drag down the mean rarely travel for regional matchups.
East's advantage appears to come from depth rather than elite dominance. When East's current top 10 face Middle's top 10, boys records are nearly dead-even (47.4%). The gap in overall cross-regional records is built in the competitive middle tier, programs that consistently reach state and win cross-regional bracket games without being national contenders.
Nashville Metro's 88 programs spread talent across more pipelines than any other metro in the state. Brentwood Academy, Franklin, and Ravenwood have elite ELO numbers, but the middle tier is shallower than the SEI advantage predicts. The concentration of investment in a few Williamson County programs likely comes at the cost of regional depth. East Tennessee's structure, three separate metro anchors each building their own competitive pipelines, produces the opposite result.
Boys: East leads in semifinalist appearances (306 to Middle's 241 and West's 181) and in championships (57 to 36 and 30) across the full dataset. The early part of the chart shows strong East dominance, driven largely by Hamilton County private schools (Baylor, McCallie, Notre Dame, and GPS) filling multiple brackets simultaneously in the late 1980s and 1990s. That pattern has spread across more programs over time. Click any bar to see that season's champions and regional breakdown.
Girls: Middle leads both categories, with 282 appearances and 50 championships against East's 267 and 39. Middle's girls advantage is concentrated in the last decade as Williamson County programs became consistent AAA and DII-AA contenders. West is last overall (199 appearances, 37 championships), but closer to the other two regions in girls than boys, and as the state cup matrix shows, West wins 72.2 percent of girls state tournament games directly against Middle when those matchups occur.
Middle Tennessee programs have lost more cross-regional state tournament shootouts than they've won, 20 wins against 25 losses. East and West both sit above 53 percent. Whether that's preparation, experience in high-leverage bracket games, or a 42-game sample that hasn't smoothed out over 35 years is genuinely hard to say. But it's consistent with the broader pattern: Middle underperforms in high-stakes, elimination-format cross-regional competition relative to what the SEI numbers would suggest.

Boys: when East's current top-10 programs face Middle's top 10, the record is 15-17-7, 47.4 percent, essentially even. East's overall 53.8 percent cross-regional win rate against Middle is built in the competitive middle tier, not at the top. Programs like West Rebels, Halls, and Science Hill, not in the national conversation but consistently reaching state, carry more of the cross-regional ledger than the marquee names do. That's the more interesting story: East's regional strength is distributed across the depth of its competitive bracket, not concentrated in two or three dominant programs.
Girls: Middle's top 10 leads East's top 10 at 55.2 percent (25-20-3), which tracks with Middle's overall girls championship lead. The girls elite level is the one place in the dataset where Middle's economic position converts most directly into results. West's top 10 holds at 55.9 percent against Middle's, consistent with West's broader girls record, driven by Memphis Metro programs whose individual SEI scores are much higher than the regional average suggests.
The cross-regional record doesn't control for scheduling bias. East Tennessee programs that travel to Nashville invitationals are self-selecting for competitive strength, which inflates East's rate relative to a fully random sample. The state tournament data is cleaner (neutral site, fixed bracket) but covers fewer games. These findings are directional, not causal.
East Tennessee's depth advantage is also unevenly distributed across Knoxville, Chattanooga, and the Tri-Cities. Treating those three sub-regions as one obscures as much as it reveals. That breakdown is the subject of a separate report. The private school concentration question and Nashville's suburban divide are also held for their own analyses.
