I think people are underestimating Aubrey. If healthy, Aubrey has had better overall statistical numbers adjusted for minutes etc, than Ice, Jana, Ashlynn, KK, and Kaitlin. Because she can guard so many positions, it might be that her best role is a super-sub getting major minutes, but she is a threat to start over any of the above as well.
That could be possible if Sarah moved to the 5 with Aubrey at the 4, and if we were bigger with Ice or Jana at the 5, Sarah at the 4 and Aubrey at the 3, or the other way around since Sarah has a superior perimeter game. I'm not predicting that will happen, but if healthy I think Aubrey is the fourth best player on the team, behind just Paige, Sarah, and Azzi, at least that's what the numbers would suggest.
She does have an issue with fitting into the half court offense, and a weak perimeter game, but she does score by running the floor, slashing to the hoop and getting offensive rebounds. Those offensive boards and also drawing fouls more than most, are areas this team is not as good at, so as long as you had at least two big time three point threats that space the floor, I think it would work fine.
Aubrey was a starter at the 3 for a whole season, and did well there, but most of her career she was behind Aaliyah at the 4, which I think is her best position. She will presumably be the obvious choice for backup minutes for Sarah, but of course that won't amount to much if Sarah stays mostly at the 4. Playing with Sarah is the way for Aubrey to get major minutes, either in combination as a 4/5, or as 3/4.
