Every Conference Realignment Move Since 2010, Mapped
98 conference changes since 2010, the collapse of the Pac-12, and the most-traveled team in America: every realignment move, mapped from the data.
Conference realignment is usually told as a story about television money, and it is. But it is also a counting problem. Our Realignment Cartographer game is built on a membership file covering 142 schools across 4,462 school-seasons, and when you lay the whole era out in rows, the shape of the chaos becomes clear: it was not a steady drip. It came in three floods, with a long, quiet river in between.
A note on method, because the numbers below depend on it. The file uses a first-played-season convention: a school is listed in its new conference starting with the season it actually played there, not the season the move was announced. A "move" in this count means a school's conference label changed from the previous season. By that measure, there have been 98 moves from the 2011 season through 2026. (One technical footnote: the raw count for 2011 is inflated because the Pac-10 renamed itself the Pac-12, which registers as a label change for every member. The real shuffles are below.)
The first flood: 2013 (23 moves)
The biggest single year in the file is 2013, with 23 schools changing leagues. This was the Big East coming apart. Cincinnati, Houston, Louisville, Memphis, SMU, and Temple landed in the new AAC; Pittsburgh and Syracuse went to the ACC; and underneath the headline moves, the WAC was dying in plain sight, with Louisiana Tech and Utah State and San Jose State scattering to Conference USA and the Mountain West while Idaho and New Mexico State dropped to independent status. A power conference dissolved, a new one was assembled from the parts, and a mid-major league ceased to exist, all in one offseason cycle.
The years around it were busy too: Nebraska had already jumped from the Big 12 to the Big Ten in 2011, Colorado and Utah had rebuilt the Pac-12, and in 2014 Louisville moved again, to the ACC, while Rutgers and Maryland joined the Big Ten.
The quiet decade
Then, almost nothing. From 2015 through 2021, the file records a handful of moves total: one in 2015, one in 2016, one in 2018, one in 2020. Seven seasons in which the map basically held still. Fans who started watching during those years can be forgiven for thinking conferences were a permanent feature of the landscape, like the field dimensions. They were not. They were between earthquakes.
The second and third floods: 2023 (12 moves) and 2024 (14 moves)
The Big 12 struck first in 2023, adding BYU, Cincinnati, Houston, and UCF — 12 moves on the board that season across the sport. Then came 2024, the year that redrew everything: 14 moves, ten of them out of one league. Oregon, USC, UCLA, and Washington went to the Big Ten. California and Stanford went to the ACC, which is a sentence that still reads like a typo. Arizona, Arizona State, Colorado, and Utah went to the Big 12. Texas and Oklahoma finally landed in the SEC. The Pac-12, which had 12 members in 2013, played the 2024 season with 2.
Look at what that did to the map's dimensions. The Big Ten had 11 teams in 2010 and has 18 now. The SEC went from 12 to 14 in 2013 and to 16 in 2024. The ACC went from 12 to 17. The Big 12 shrank from 12 to 10 in 2013, then ballooned to 16. The FBS itself grew from 120 schools in 2010 to 138 in 2026. And the Pac-12 story did not even end with the collapse: the file's 2026 rows show a rebuilt Pac-12 back at 8 members, with Fresno State among the schools wearing its third different conference label of the era.
The story is still moving, too. The file's final season, 2026, records 9 more moves, six of them into the rebuilt Pac-12: Boise State, Colorado State, Fresno State, San Diego State, and Utah State out of the Mountain West, plus Texas State from the Sun Belt. Louisiana Tech went back to the Sun Belt, Northern Illinois left the MAC for the Mountain West, and UTEP did the same from Conference USA. A league that was left for dead with two members in 2024 recruited its way back to eight in two years, mostly by raiding the league below it, which is how every league in this file has ever grown.
The most-traveled team in America
One school has changed conferences four times since 2010, and it is New Mexico State: WAC to independent, independent to the Sun Belt, Sun Belt back to independent, and finally into Conference USA. Four moves, four conferences, and two separate stints with no conference at all. Runners-up form a three-conference club that includes Arizona and California (both on paths nobody would have drawn in 2010: Pac-10 to Pac-12 to the Big 12 and ACC respectively), BYU, Cincinnati, and Houston.
Why a map game
Realignment is the rare sports story you can literally quiz. Every one of these 98 moves is a fact with a season attached, which is why the membership file powers Realignment Cartographer: we name a school and a season, and you place it in the conference it actually played in that year. Nebraska in 2010 is a trap. California in 2024 is a trap. New Mexico State in any year is a trap. The map stopped making sense years ago; the least we can do is make a game out of keeping it straight.
