I'd imagine even with poor seasons, both would be kept (possibly less sure of Maric being kept). However I think it's important for their development, and establishing a solid future at the club in a meaningful role, that Maric has a good year where he shows his ability at younger levels can be translated into the AFL while Petterd needs to show that he's not a player who can play bit roles well, but rather that he can cement a position for the future.
Odd reply by the way
