I'd like to see Grimes play a game this year. I like how Malthouse does things by given a debut, a taste of AFL and leave it with the individual.
Grimes can play deserves a debut and would be good development wise coming into the pre season knowing whats required for AFL standards.
In: Jackson, Grimes
Out: Nahas, Thurstfield
Nahas unfortunately may have played his last game, I'm not 100% seeing him being delisted but he needs some serious weight behind him. He's be 23 before the year is out, needs some weight.
I also really like the Post/Graham ruck combo. Saints didn't have a decent ruckman so we could experiment, Brogan and Trengrove don't worry me I think we can try for this again.
