Do you have cash in the bank?
Humps, Arthur, Leota and Vaimauga are a sell. Humps to Fogarty unless you're happy with two halves until origin. If you have no cash and happy to run two halves then, humps and Leota or Arthur to two cash cows.
You also have option to get a better hooker or second one. You really shouldn't go Egan with your 4 warriors. Reed Mahoney is cheap and scores well.
Otherwise your team is looking good. Great forwards and edge. Your centers are sorted.
