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 A.R. McLean Medal is awarded to Port Adelaide's best and fairest player in the SANFL. After the completion of every game, Port Adelaide's SANFL coaches and SANFL Manager Shane Grimm cast their votes, rating each player's performance between 0-5, with a maximum of 20 and minimum of 20 votes per player per game awarded.

The same process is undertaken in the AFL, with the Power's best and fairest player receiving the John Cahill Medal.
