Although Jovic had a fantastic rookie year, she will need to back this up next year as a second year player that everyone has had a chance to look at and then will be deserving of inclusion in one of the squads.
Note that everyone else is at least a 2nd year player (even if they first got SSN court time mid way though season 2019), so not only “broke through” but also backed it up.
I imagine these selections – like for Diamonds – are based on strict guidelines, monitored over a 3 year period.
You can hardly call Manua, Poolman, Scherian and to a lesser extent Stanton “development” options. All except Stanton have been in & now dropped out of Diamonds & Stanton probably had insufficient court time (or form) to warrant selection.
Congratulations to all selected!
