I would be happy with Croft if he can get his bad habits out of his game.
When he's playing simple footy, he's a good halfback and he'll be a good foil for Milford. It could be a very successful halves pairing. However, he has a habit of overplaying his hand which is one of the reasons why he is in and out of the Melbourne side. He keeps trying to come up with the miracle play, especially when the Storm are behind. He just needs to play simple footy. Guide the forwards, do the kicking and let Milford do the rest.
If he can do that, he'll be a good signing.
