The Purple Knights have not won a league game since December 2013, a futile string of 49 straight setbacks against their rivals.
Teshonna Bennett's first Memorial squad never tasted victory last year, something the program hasn't done since the season opener in 2014-'15.
This year's chances for improvement will depend on players such as senior Sydnee Marshall (4.4) and juniors Aniah Williams (11.1) and Nadiya Connor (5.8).
Kerry Storbakken's Cougars fell one game short of a third consecutive 20-victory season, finishing 19-7, including a 14-4 mark and third-place showing in league play.
Craig must replace one of the program's top players for a second straight year, losing conference scoring leader and first teamer Delaney Schoenenberger a season after Alison Hughes graduated.
Annie Schumacher (13.0) and Kamryn Brittingham (8.4) also are gone. However, the Cougars' lineup still features Ali Carlson, who made the third team after averaging 8.8 ppg, and fellow senior Sam Pierson (5.1).
The Vikings' 9-9 record placed them fifth in the always-tough league race. That helped them finish 14-10 overall, losing four contests by four or less points during Jennah Hartwig's first year after replacing Wisconsin Basketball Coaches Association Hall of Famer Tom Klawitter.
Parker also must replace its best player in league first team choice Bree Porter, who topped the team at15.4 ppg, reaching double digits in 22 of 24 outings.
While Porter has taken her skills to NCAA Division II school Hillsdale (Mich.), the Vikings' fortunes will hinge a lot on senior Julia Hartwig. She led the Big Eight in rebounding (11.0) and averaged 15.3 ppg.
Also back are senior Kameron Blaser (5.6), sophomore Brooke Graesslin (4.0), junior Jacy Benway (3.7) and senior Sydni Brewster (3.1).
