This is true, and again it's where I think the AFL system is fairer. Top 4 know if they lose in week 1 they get a second chance, and will play a team below them. Bottom 4 know if they lose in week 1 they're gone, and that they will keep getting harder games as they go.
All teams know from week 2 on there's no second chances.
The only difference with the AFL method I would have is venue allocations. I would keep the NRL method where if you win in week 1, you play your next game at home.
Let's just assume:
Week 1:
Melbourne lose to Tigers @ AAMI Park (on week 1 form, I think that would've been likely)
Manly lose to Brisbane @ SFS (also on week 1 form, I think that would've been likely)
Dragons def Knights @ SFS (Knights out)
Warriors def Cowboys @ North Harbour Stadium (Cowboys out - was probably a bit of a cripple fight based on week 1 form)
Week 2:
St George-Illawarra def Melbourne @ SFS (again, based on week 2 form, Dragons were superb)
Warriors def Manly @ Auckland (maybe wishful thinking)
Week 3:
Broncos def St George-Illawarra @ Lang Park
Warriors def Wests Tigers @ SFS
Week 4:
Broncos def Warriors @ ANZ Stadium
*sigh* If only.
