If you have the cash, $168,500, Cam  O'Shea  from Port should play the season on the wing. Was out most of last season and so comes in very cheap. Has played all NAB games on the wing, don't know how he will go score wise but will make you $$$s.
Out of the players you mentioned I went for Stevenson, had a good 1st season for WCE then starved for chances last year and so traded to Port.
