They're the five risers  of the competition, those who have made the biggest jumps of anyone in the competition. 

Champion Data, using its Official AFL Player Ratings, compared every individual's performances from last year to this year.

It's a measure that considers a variety of stats to come up with a score to judge how effective players have been. 

To qualify for this exercise, players need to have lined up in at least 15 games last season and nine this season.

The risers

1. Brandon Matera (Fremantle)
Talent was never an issue for the left-footer, stretching back to his Gold Coast days, but the 27-year-old is now putting it all together. He's booted 24 goals from his 11 matches, is converting his shots at 11.4 per cent higher accuracy and has tripled his forward 50 marks per game to 1.5.

2. Ricky Henderson (Hawthorn)
What the one-time delisted free agent is doing is pretty phenomenal. At 30, he's producing easily the finest footy of his career. Compared to 2018, his average disposals have increased by 7.1, to 27.4, and he's going at 8.2 marks per game to rank sixth in the competition.

3. Travis Boak (Port Adelaide)
The former Power captain is defying belief with his exploits. Last season, it looked like his career might be winding down. Scotch those thoughts. Boak is flying and his coach Ken Hinkley believes the 30-year-old has never played better. His average contested possession count has spiked by almost six, up to 15.2 per game, ranked No.6 in the AFL.

4. Darcy Tucker (Fremantle)
Another of the reasons Freo has emerged as a finals contender. Having shifted from half-back to an onball role, Tucker is winning more of it (his average disposals have lifted by more than five to 19.7), his pressure points have gone up from 33.4 to 41.6 per game, while his score involvements have improved to 4.6.

5. Hugh McCluggage (Brisbane)
In his third year, it's no surprise this classy jet has gone to another level. He's added goalkicking to his arsenal, going at 1.2 per game, up from 0.5, is collecting more of the footy and his average inside 50s have swollen by almost two, up to 4.5
