Each week, ESPN.com.au AFL draft expert Chris Doerre casts his eye over the country's best junior footballers to give readers an early insight into the next generation of AFL stars.
As well as attending live games, Doerre pores through match vision, analyses the stats and talks to industry sources to ensure he can offer the most insightful draft analysis.
Aside from the weekly wraps, Doerre will also unveil his power rankings at the end of each month and as we get closer to November's national draft, Doerre will also predict who goes where with his annual phantom draft.
Anyone attending an under-18 game can recognise who the top-end talents are but figuring out the bargains who may be available late in the draft, or even be picked up as a rookie, is also crucial.
Similarly, the mature-age state league standouts are easy to spot as they strive for a chance to prove themselves at the top level.
But who are the unproven youngsters who could be the biggest draft bargains? The following 10 players under the age of 20 have shown enough to suggest they could be the biggest steals of the draft. They are listed alphabetically.
Jordon Butts
Position: Key defence
Expected draft range: Late-undrafted
Why he can make it: One of last season's most impressive key position players, achieving a competition high 7.5 marks per game, Butts returned to Murray in the TAC Cup and was again prolific. In two VFL games, he held his own and managed 10 marks in his second match, placing among Werribee's bests.
Jarrod Cameron (WCE Next-Generation Academy)
Position: General forward
Expected draft range: 30-late
Why he can make it: Sharing the same gifts as his brother Charlie, Jarrod possesses comparable speed and forward pressure. He announced himself against Vic Country, kicking a game-high five goals. What has made Cameron's performances noteworthy is how exceptional his play has been despite hip issues he has carried since the start of the season. Cameron will need to get stronger to ensure his tackles stick because he can become a valuable forward at AFL level as Charlie before him has.
Noah Gown
Position: Key forward/key defender
Expected draft range: 40-undrafted
Why he can make it: With one of the strongest finishes to 2018, Gown was among Gippsland's bests in each of their last 10 matches, managing TAC Cup-highs of 21 goals and 19 contested marks in his final seven matches. His play as a key forward was not far off the high standard set by likely top-10 pick Ben King. In the assessment of key forwards, production and rate of improvement are keys in projecting whether they will develop. With the way Gown reads the ball in flight, attacks it aerially and how strong of a contested mark he is, he could be just as good as a key defender.
Marcus Lentini
Position: Inside midfield
Expected draft range: Late-undrafted
Why he can make it: Averaging competition highs in contested possessions and loose ball gets in the VFL, Lentini is one of the most ready-to-go midfielders outside the AFL. Lentini impressively achieved these numbers as an overager. A stoppage specialist, he can step into a midfield and contribute from season one. If his kicking improves, Lentini can have a long AFL career.
Connor McFadyen (Brisbane Academy)
Position: Inside midfield/general forward
Expected draft range: 20-40
Why he can make it: A powerful contested ball-winner at 190cm who distributes effectively by hand. He is equally gifted up forward as a marking target, protecting the drop zone, displaying strength one-on-one and is clean at ground level. Impressively, McFadyen arguably looked like the Allies' best midfielder and forward during the Under-18 Championships. His play in the NEAFL has been notable for Brisbane, kicking six goals from five matches.
Mitch Podhajski
Position: Inside midfield/general forward
Expected draft range: Late-undrafted
Why he can make it: Progressed from a 191cm defender in 2017 to take the next step as an overager this year in becoming a dominant midfielder. Podhajski has been prolific during 13 TAC Cup games, kicking 23 goals and establishing himself as one of the competition's premier ball-winning midfielders. Even more impressive, in each of Podhajski's last six VFL matches, he had at least 19 disposals and four tackles while kicking five goals during that span, suggesting he is AFL ready.
Jack Ross
Position: Inside midfield
Expected draft range: 30-rookie
Why he can make it: Arguably Oakleigh's most consistent draft-eligible talent following the conclusion of the Australian Private School Football season - on an Oakleigh team that includes projected first-round choices Riley Collier-Dawkins and Isaac Quaynor. Ross, who remains one of this year's underappreciated midfielders, is a powerful contested ball-winner who does his best work at stoppages while possessing reliable skills.
Tom Sparrow
Position: Inside midfield
Expected draft range: 30-rookie
Why he can make it: Arguably the most aggressive prospect in the draft, Sparrow attacks the ball and tackles with an intensity like no other. He has featured among the bests in all eight of his SANFL Under-18s games. Sparrow shows hints of Patrick Dangerfield-like ball winning and acceleration away from the contest. Agility for someone with his strength further sets him apart.
Sydney Stack
Position: Inside/outside midfield
Expected draft range: 30-late
Why he can make it: One of this year's most exciting talents, Stack is a one-touch ball-winner at stoppages, winning the ball on the move, using speed and evasion to burst out of stoppages and manoeuvring around opponents with ease. Beyond his ball winning and movement, his skill and composure in traffic set him apart from his peers. Averaging 22 disposals, 11 contested possessions and five clearances during the Under-18 Championships and 14 disposals in the WAFL at League level, Stack is a rare high impact-per-possession player with an established contested side to his game and strong production at all levels of play.
Boyd Woodcock
Position: General forward/inside midfield
Expected draft range: 30-late
Why he can make it: A pesky, opportunistic forward. Woodcock kicked eight goals in the SANFL League finals for North Adelaide in their premiership run with all eight coming in his final three games. The 174cm forward has the capability to push up through the midfield, with a season-high 43 disposals, 24 contested possessions and 18 clearances in round three of the SANFL Under-18s.
