YOU DECIDE: These are the moments at the heart of tanking allegations against Melbourne.

Former Demons coach Dean Bailey and club officials Chris Connolly and Cameron Schwab have been asked to show why they should not be charged with offences including draft tampering in 2009.

That was the season Melbourne won just four games to qualify for a priority draft pick, which allowed the Demons to recruit Tom Scully and Jack Trengove with the first two selections in the national draft.

The club has received a 1000-page dossier containing the findings of the league's five-month tanking probe.

The AFL is understood to have interviewed about 20 people, including current and former Melbourne staff and players, about the club's on-field intentions in 2009.

Those interviews are believed to have focussed on the Dees' Round 18 loss to Richmond, when Jordan McMahon kicked a goal after the siren to get the Tigers over the line by four points.

A review of the tape by SuperFooty has revealed several bizarre moves by the Demons' coaching box.

The most unusual was Melbourne's forward set-up at the start of final quarter, when they led by three points.

The Dees' forward line consisted of regular key defenders Matthew Warnock (full-forward) and James Frawley (centre half-forward) with top ball-winner Nathan Jones and tagger Clint Bartram in forward pockets, plus veteran Aaron Davey.

Only Davey had any history as a goalkicker. Warnock and Frawley had kicked one goal each for their careers to that point, and neither went close to adding to their totals that afternoon.

With its defenders in the forward line, Melbourne had regular forwards Brad Miller and Matthew Bate playing as onballers in the centre square. Miller (194cm) was matched up on a young Trent Cotchin (185cm).

At other stages in the game Miller played in the ruck while 199cm Paul Johnson played full-back for most of the day, opposed to Jack Riewoldt and Nathan Brown.

Brown kicked a crucial goal during the final quarter while directly opposed to the 18cm taller Johnson.

Melbourne made just 47 interchange rotations that day, their fewest of the season and way down on their season average of 85.

There have been suggestions questions were asked about whether players fumbled deliberately in the dying minutes, but Melbourne kicked two goals in time-on to pinch the lead before McMahon's heroics.

And Richmond players made their share of mistakes as well.

Nathan Brown summed it up in a post-match interview: "It wasn't the greatest game in the world, but it's good to get the points."
