NZ, Perth and Wollongong had such a big advantage last season because of their continuity. Townsville would have too if they had not completely stuffed up with their imports.
Those teams averaged eight returning players where the others averaged five. This year that has disappeared a little bit, NZ still in front with seven but a lot of teams with six.
In terms of returning starters, NZ, Perth, Cairns and possibly Wollongong will all be bringing back four (depending on Hurdle), and that has to help.
NZ 7 returning this year, 4 starters(8 last season, 4)
Perth 5, 4 (8, 5)
Wollongong 6 or 7, 3 or 4 (8, 4)
Sydney 4, 2 (5, 2)
Melbourne 6, 2 (5, 1)
Cairns 6, 4 (6, 3)
Townsville 5, 2 (8)
Adelaide 6, 4 (4)
