Much of what you say is very accurate, but not all of it (per my recollection). Nicole Wolff did indeed suffer a stress fracture in her freshman year, and that kept her out of serious action until her junior year.
In both her junior and senior years, she was physically healthy by all accounts, showed outstanding effort in practice and led the team in fitness measures. But at that point (for reasons that remain unclear) she suffered from "above the shoulders" issues and couldn't translate her outstanding practice performance into game performance. Geno gave her every opportunity. He made her team captain and also made her a starter in both years (as I recall). She did well defensively (except when she tried to guard Seimone Augustus and the small quick guard from North Carolina whose name I have forgotten). But she never got untracked at the offensive end, so Geno couldn't give her major minutes.
Her issues in her junior and senior years seemed to me to be similar to those of Molly Bent in a later era -- mostly not of a physical nature. I hope it isn't endemic to players from southeastern Massachusetts, or (if it is) that it doesn't affect Caroline Ducharme.
Although Azzi can be harshly self-critical, I don't think she is the kind of person who is likely to have disabling non-physical issues. If that is true, then the precedents of Nicole and Molly shouldn't be expected to apply to her.
