AFL players don't do much that isn't tracked, analysed and reported on.
Every training session and match day, GPS devices worn just below the collar at the back of each guernsey send live data to club fitness staff.
With the help of the Telstra Tracker, Cats Media has taken a look at the GPS numbers behind Geelong's best athletes.
