Leagues of Their Own: 3 Power Conferences Provide > 3 Teams in Sweet 16
Packing the court legitimately, three power conferences combined to provide all but one of this year's Sweet 16 participants (featuring all-time record seven for the SEC after alliance started with all-time high of 14 delegates). It is a dramatic turnaround for the SEC, which supplied more than two Sweet 16 representatives only once (three in 2007) in a 12-year span from 2001 through 2012 (marred by a goose egg in 2009).
In 2016-17, the national media proclaimed the ACC as perhaps the greatest league in history but that assessment came before the nine-bid alliance was fortunate to have one representative among regional semifinalists (North Carolina overcame five-point deficit in last three minutes against Arkansas). #MessMedia proclaimed the Big Ten as dominant three seasons ago but only one of nine participants survived the first weekend of competition. The Big Ten became the first conference securing at least nine entrants in single tourney and have none of them advance to a regional final in 2022.
In 2009, the Big East became the first conference to boast five playoff teams reaching the regional semifinals in the same year until the ACC duplicated the feat three years ago. The ACC boasted four members advancing that far on eight occasions in a 12-year stretch from 1984 through 1995.
The ACC in 1985 was the only league in this category not to have at least one of the quartet reach the Final Four until the Big East was foiled in 2006. The following list of thoroughbred leagues supplied at least four Sweet 16 participants a total of 33 times since the NCAA Tournament field expanded to at least 48 teams in 1980:
x-Won NCAA championship
y-Finished national runner-up
z-Reached Final Four
Duke's success this year enabled the ACC to extend its streak of Sweet 16 representation since 1979 when the field expanded from 32 to 40 teams after the Blue Devils reached the 1978 tourney final. Duke and North Carolina both lost their openers in 1979. Despite struggling of late, the ACC is the only league not to be shut out of the Sweet 16 at least once since the Big 12 Conference's inaugural campaign in 1996-97. The disbanded Pacific-10/12 Conference was nowhere to be found in the Sweet 16 five times in an eight-year span from 1980 through 1987. Following are the years since 1979 when power conferences failed to have at least one member reach the Sweet 16:
ACC - 1979
Big East - 1986, 1993, 2019 and 2025
Big Ten - 1995, 1996 and 2006
Big 12 (plus Big Eight and SWC) - 1990 and 1998
Pacific-10/12 - 1980, 1981, 1983, 1986, 1987, 1999, 2004, 2012 and 2018
SEC - 1989 and 2009
