Comparing current players with others seems to be a legitimate Boneyard exercise so let me take a turn.
The player that Gabby reminds me of most is Ashley Battle, a classmate of Diana (and Maria, Jessica, and Morgan I). She was never a prolific scorer (7-8 ppg) but a good rebounder for her size (about 5 per game). What she really was to her 3-NC team -- AB was a lock-down defender, for which she was often honored,
I categorize Gabby as a "swing," and expect her role to be early (maybe first) off the bench to provide a break for another swing (likely) or even a big or a wing. But most important, Geno can say "sic'em" and send her after most any opponent with a hot hand, then count on Gabby to cool her off.
