League of Their Own: No Power Conference Supplied Four Sweet 16 Teams
Packing the court legitimately six years ago, the ACC set an NCAA Tournament record with six Sweet 16 participants. No power league had as many as four this year. 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) and failed to produce a single individual among 19 All-Americans last season. #MessMedia proclaimed the Big Ten as dominant last season but only one of nine participants survived the first weekend of competition. The Big Ten, after having three NCAA consensus first-team All-Americans out of commission prior to Sweet 16, became the first conference securing at least nine entrants in single tourney and have none of them advance to a regional final.
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 two 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 30 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
