We've put a player from every club under the microscope that need to put in a big pre-season.
Whether it's a young player that needs to break out or put on some size, a veteran that needs to rediscover a spark or a star returning form injury, the following names need a big summer.
Brisbane
Oscar McInerney
With Stefan Martin 32 and entering his 13th year of AFL footy, his time as the Lions' number one ruckman could be coming to a close. This opens the door for Oscar McInerney to stake his claim for the job. The young Lion has played 37 games in his two years at the club, playing as a back-up ruckman and rotating forward.
Brisbane delisted Archie Smith, who was expected to be Martin's understudy, this offseason, meaning they could have their sight set on the "Big O" taking the role. At 204cm and 107kg, McInerney certainly has the size to fill Martin's shoes, and this pre-season could be spent further preparing the 25-year-old for the job.
