The first thing I would like to see from Amari (and I suspect that Geno would agree) is a readiness to mix it up under the basket -- protect the rim on defense, box out, contest rebounds, hang onto rebounds when she gets them, look first for a putback rather than someone to pass to, and (in general) don't pass unless/until she is double-teamed. After she shows those credentials, shooting from 10 or 15 feet may be the next priority, but it's somewhere quite a ways down the list.
If she just wants to be a big who can make midrange shots, there are other players on the roster (Aaliyah, Ice, Ayanna, Caroline, maybe even Aubrey) who can do that -- and those players can also attack the basket and contest rebounds. For Amari to make enough of a contribution to get serious minutes, she needs to use her 6-5 frame and be a credible backup for Dorka or Aaliyah when they are unavailable for whatever reason.
