If you are so positive that they will win, you would be stupid to only put $10. You are sitting on an unclaimed fortune here. Whack all of your savings on them!
I think Manly will go close to making the 8, but I can't see it happening. The competition is so different to a coupla seasons ago. You could always bet that the 8 would consist of:
Brisbane
Bulldogs
Knights
Roosters
Sharks
Dragons
Parra
and 1 other surprise team
Now, all of those teams could make the 8, plus
Canberra
Storm
Tigers
Cowboys
Penrith
Warriors
So in my opinion, there are only 2 out of 15 teams that can't make the . Manly, and Souths. The even comp is due to salary cap. Makes for exciting season
