The problem Cox has is when he does not Mark it he is a liability. I like him and would love him to succeed. Have met him and he is genuinely one of the better blokes you would meet. His attitude is first rate. But unless you are a full time ruckman or have unbelievable athleticism (good at ground level and super quick) its just hard to see a bloke of his height making his mark as a forward in this day and age.
