They are points if for the majority of previous season they played A Grade.
So, if I recruited you MC, for example, and you had played eight A grade and nine reserves matches, 0 points?
Yep, If I had played 8 A Grade and 8 Reserves I'm still 0 points because I havn't played the majority A grade games.
However, Im not sure you could stretch the budget far enough. But you can try! :D
