I didn't say he was as quick or agile as Crisp. All I was pointing out is that a guy who is 2cms taller is playing as a ground level back pocket/half back. And it has no bearing on his ability to play the role. And it doesn't make him an intercept defender. Fair enough if you feel Crockers speed or agility will limit him in the role. I'd disagree.
I'll add, just because Crocker is a marking forward it doesn't necessarily follow that he has to be an intercepting defender. But it does mean if he is in a marking contest he knows how to stand up.
I think we are clutching at straws trying to turn crocker into a defender. Delist and go back to the draft , costs us nothing , however if we persist and he still doesn't turn out we have denied a spot to a kid on our list. To me he hasn't stood out for any attribute in the little games he has played for us , apart from toughness
