The trio have enjoyed career-best seasons at Port Adelaide, which have also led to them being nominated for the 2014 AFL Players Association's Leigh Matthews Trophy for the League's most valuable player.

Boak, an All-Australian in 2013, has again shown his worth as the Power's skipper this year with another consistent season playing through the middle of the ground and often being forced to deal with some of the competition's best taggers.

Gray's career-defining performance this season led to him being voted the best player in the League by the AFL's coaches in the 2014 AFLCA Champion Player of the Year Award. 

He is one of the favourites to win this year's Brownlow Medal, and is certainly likely to win this year's John Cahill Medal as Port Adelaide's best and fairest player.

Schulz has also enjoyed one of his best seasons, having led the Coleman Medal race midway through the year and set to win yet another club leading goal kicker award. 

He has currently kicked a resounding 62 goals before the club's first final against Richmond this weekend.

The All-Australian team will be finalised next week.
