But Collingwood's Scott Pendlebury and Hawthorn's Josh Kennedy continue to keep things interesting.
While the Brownlow Medal voting is done by field umpires on a 3-2-1 basis, Sportingbet have developed a structure to predict the overall winner using a rolling leaderboard and analysts providing their own votes weekly.
Sportingbet’s AFL analysts awarded Ablett ($1.50) and Pendlebury ($8.50) 2.5 votes and Kennedy ($9.50) 2 votes for their Round 15 performances.
Ablett remains six votes clear of Pendlebury and seven votes ahead of Kennedy with eight rounds left of the regular season.
Sportingbet’s analysts award half votes when they can’t split certain player performances, a system that has proven to balance out over the course of the season and provide a more accurate prediction of a player’s final vote numbers.
Richmond's Trent Cotchin, Lion Pearce Hanley and Docker Stephen Hill all received maximum votes.
