Regarding forwards, baby Mellon is your natural finisher but needs workers around him.

Drummond is inconsistent and can easily be marked out of a game.
Fondop will play a more minor role i think this season because Mellon senior will try other partnerships. Big Mikey is 32 now and is asked to play in defence as well as up front which isn't easy for a big man.
Kavanagh is not good enough from the little we have seen.

If the Mellon jnr and Fondop duo clicked(maybe fed by the drummer boy or a wide man) it would bag 25-30 goals combined in my opinion.
