AHEAD of Port Adelaide’s Best and Fairest count on Friday night, portadelaidefc.com.au takes a look at who is in contention for the John Cahill and A.R. McLean medals.

The John Cahill Medal is awarded to Port Adelaide’s best and fairest player in the AFL. After the completion of every game, Port Adelaide’s coaches and General Manager – Football Chris Davies cast their votes, rating each player’s performance between 0-5, with a maximum of 20 and minimum of zero votes per player per game awarded.

The same process is undertaken in the SANFL, with the Magpies’ best and fairest player receiving the A. R. McLean Medal.
