From looking at the last 10 years of womens' basketball NCAA tournaments, this year had the fewest low-seeded teams in the sweet sixteen:
2013: 12 seeded Kansas
2014: 12 seeded BYU, that gave UCONN a hard time at the regionals
2015: 11 seeded Gonzaga
2016: no double-digit seeds, but two #7
2017: 10 seeded Oregon with Sabrina Ionesco and 12 seeded Quinnipiac
2018: 11 seeded Central Michigan and 11 seeded Buffalo
2019: 11 seeded Missouri State
2020: No tournament
2021: 3 6-seeded teams
2022: 10 seeded South Dakota and 10 seeded Creighton
2023: Two #1 seeds didn't make the Sweet Sixteen, Indiana and Stanford
A couple of other thoughts, UCONN has been in every Sweet Sixteen since 1994.
UCONN has won at least 30 games in years since 1994 except the 2004-2005 (first year post-Taurasi) when they were 25-8; 2019-20, when they were 29-3, but the tournament was cancelled, and 2020-21, they were 28-2, but 6 games were cancelled because of COVID.
Finally, beware of Duke, remember the 2006 regional final, Duke 63-61 in overtime
