Furthermore, Fremantle captain Nat Fyfe could finish with the most votes, although his one-match suspension for striking Collingwood hard nut Levi Greenwood in round 11 means he's ineligible.

With one home and away game left, reigning winner Dustin Martin sits ahead of the field on 22 votes.

On 21 are Carlton onballer Patrick Cripps, Hawthorn ball-winner Tom Mitchell, West Coast star Elliot Yeo and Melbourne ruckman Max Gawn.

Then with 20 are Fyfe, Collingwood big man Brodie Grundy and brilliant Brisbane midfielder Dayne Beams.

However, BetEasy has Mitchell as the raging favourite to win 'Charlie' at $1.25.

Cripps is on the next line of betting at $10, Martin is $13, Gawn is $15 while Beams is $16.

Young Melbourne jet Clayton Oliver is next at $17, and following him, Yeo is $23 while Grundy is $34.
