Silver Ferns coach Waimarama Taumaunu is closely monitoring the workload of Mystics utility Kayla Cullen this season.
The loss of several experienced players has elevated Cullen to a key member of the Auckland side this year as she faces the added challenge of switching from the defensive end to the midcourt.
With the retirement of Temepara George and loss of Charlotte Kight to injury, the Mystics are light on experience in the middle, placing a heavy burden on Cullen to get up to speed in her new role.
A lot will also be asked of her during the international season, with the young Silver Fern selected in the New Zealand under-21 side for this year's World Youth Championship in Glasgow.
Following the transtasman league season, Cullen will link up with the under-21 side to prepare for the World Youth Champs in August - an intense week of tournament play that will require strong conditioning from the athletes.
