I noticed Anduril asked about why Pro stats don't have effective kick % on their website, can't answer that question, but I can give you some stats if it's any help.

Obviously, that doesn't take into consideration different players roles (ie our Rucks are more likely going to grab the ball from the middle and just kick it forwards without being able to size up an appropriate target, whereas a running half back, should have a bit more time to look up field and pick out his man.
Other players (Eg Humm, Knobel, Thursfield, JON and McGuane) have played very few games, and have had little chance to correct a poor start. Others (Like Howat) started out incredibly well, and are just starting to come back to the pack as more games are played.
Makes for some interesting reading nonetheless. I do have some figures from previous years as well, if anyone wanted to know how a particular player has improved/declined over time.
Forgot to mention these stats came out of the AFL Record from Round 21, for those who hadn't got the chance to get a copy.
