Against more ordinary teams, Uconn frequently has bench players that are as good as the other teams best starter. Look at the 2016 championship team. Number 6 & 7 were Pheesa and Gabby, both future proven WNBA players. 8 & 9 were Sonia Chong and Natalie Butler. Both were drafted by the WNBA, Sonia played a year, and Natalie after she transferred led the nation in rebounding the next year. Courtney Ekmark was #10, and she transferred and became a starter for a Power 5 conference team.At UConn they might be pretty good.
Expected players for this season included Paige, Fudd, Dorka, Edwards, Griffin, Ducharme, Muhl and Lou. That’s 8 so I’d say 7 and 8 are pretty good,
One of my favorite teams was 2000-01. At the start of the season the starters were Shea, Svet, Sue, Swin and Kelly Schumacher. That left Tamika Williams, Asjha Jones and DT as the 6th, 7th and 8th players so the 7th and 8th players weren’t too shabby.
Or how about Kia Stokes who was never a regular starter in her career here because of Stewie and Stephanie, but she just got her championship ring this year with the Aces. As you mention DT was not an immediate starter. In fact Shea Ralph's greatest claim might be for a season she kept Dianna on the bench.
More recently before her injury Mir was having a great season at Virginia, but got little time here. Saylor was a third stringer here starting at Arkansas. Espinoza-Hunter was a big scorer at Seton Hall and a non-factor here. The examples are really too numerous to mention. Most of the top programs, not just us, but also teams like South Carolina and Stanford have bench players that are usually significantly above average, with several that could be stars at most college programs. The top contenders sometimes don't have anybody that is below average or a weak link in their rotation. Their backups are usually highly ranked recruits.
