Backs:
B Goddard, H Shaw, Deledio, R Murphy, A Otten, Tarrant, Toy
Hibberd, Puopolo & Duigan
Mids:
Swan, Bartel, Judd, Montagna, Burgoyne, Heppell
Harris, Atley & Mzungu
Rucks:
Sandilands, Jolly
Z Smith & Derickx
Forwards:
Goodes, Pavlich, Rioli, Higgins, Yarran, Knights, Krakouer
Prestia, Tapscott & I Smith
From that, I would recommend downgrading Knights to Brendan Matera, saving 120k. Also, get Cam Richardson in your forwards as he should play, and should score well.
Then use that to upgrade Murphy to Gibbs in your backline, and because of your super strong mids, I think your team would be almost set. (Oh, and David Swallow from GC will be a bit of a gun, possibly replace him for Mzungu depending on cash)
Decent effort from someone with glandular fever
