He is the complete midfield package with his contested ball work just as deadly as his run and carry. He also kicks well on both feet and is strong overhead.
So impressive has the Sun's form been, it prompted Essendon great Tim Watson to declare: "Jaeger O'Meara could quite well go down in history as the greatest midfielder that's ever played the game."
It is not hard to see why he's odds-on favourite to take out this year's award.
Like O'Meara, he's just as adept at winning the hard ball as he is at cutting the opposition to pieces with his outside run and sharp foot skills.
The 19-year-old should be proud of a debut season that has seen him averaging 24.5 disposals, four marks and four tackles across 14 games.
While the 21-year-old has taken time to find his feet at Arden Street (nine games in two years), it has definitely been worth the wait.
Mullett, who did not miss a game this season, is the man the Roos want with the ball in his hand, as his laser-like left foot has set up many a forward thrust.
And he also knows were the big sticks are too, kicking an impressive 14 goals and just the one behind while averaging almost 19 touches a game.
A leading forward for much of his highly decorated junior career, the 19-year-old has played predominately on the wing in 2013, winning a lot of the ball, and admirers, along the way.
The South Australian has averaged 16.7 disposals a game but is working tirelessly to add a defensive edge to an arsenal that features sure foot skills, composure and an uncanny ability to find space.
Wines' manic approach to winning the ball didn't end there, with the 19-year-old taking on some the League's toughest midfields to average 19 possessions and four tackles across 22 games so far this season.
He's worked hard to refine his kicking and spread from the contest but he's gone a long way to justifying Port Adelaide's decision to take him with pick seven in last year's draft.
