Fremantle's Nat Fyfe says he is up to 4kg heavier than at the same time last year and aiming to exert an even stronger presence in packs.
And the 21-year-old has nominated Cameron Sutcliffe as the club's emerging midfielder to look out for as the Dockers aim to build a deeper, stronger engine room.
Fyfe, given part of the summer off to make sure he was not overworking his growing body, started last season at 85kg but would look to play at around 89kg this year.
The extra bulk was a combination of his natural growth and a decision to add a little weight.
"I don't want to be too heavy so I lose run, but this year is a bit about getting to know what it is like to play at 89kg and if I need a bit more next year I can always go up. But I am pretty comfortable and confident with where I am at the moment," Fyfe said. "Hopefully I will just be able to stand up in packs a little better this year."
Fyfe has been such a revelation in his first three seasons that he will start the season well inside the top 10 fancies for the Brownlow Medal.
But after missing 13 of Fremantle's 24 matches last year with shoulder problems, playing consistently for a full season was far higher on his list of priorities than the game's highest individual honour.
"I am more keen this year to have my body ready to go in round one and try to sustain that throughout the full season," Fyfe said.
He was confident he was over his shoulder problems.
"I am pretty confident that I have done all of the work I can, so there should be no problem hopefully," Fyfe said. He said 20-year-old Sutcliffe, who broke into the team last year and played four games, had the capacity to become an elite player.
"His running ability is first class and his ball hunting ability is one of his skills," Fyfe said.
Meanwhile, the Dockers and Adelaide have agreed to play a pre-season practice match on February 23, during a break in the NAB Cup schedules of both clubs.
The trial game is likely to be in Adelaide.
