Good decision to re-sign Cale.
He is quick, covers the ground, knows where the ball is going, but needs to learn the contact aspects.
That last is down to coaching, personal confidence and confidence in the game plan.
Most young players come into the competition a little tentative. They can kick, mark, run, etc, but need to be taught footy is a big boy's game and that they need to know how to approach a contest. Cale, in my opinion, has been poorly coached in how to win tough footy. Had he been at, say, Collingwood Malthouse would have worked on his pressure skills and he would already be aware of how to attack a contest.
Also, when players have confidence in the game plan, they automatically do the right thing. They know that if they are going to cop heat, they can give it to a person in a better position. Strikes me that Calelacks confidence approaching the ball, because he doesn't know what he has to do once he gets it.
Badly needs a new and better coach whose emphasis is on footy as a contact sport.
