Jamar ahead of PJ easily. His ruckwork is excellent, and he can take an overhead mark.
I like Johnson, but I think he is more of a forward who can ruck, than a ruckman who can go forward. And even as a forward, he is questionable because he can't actually mark very well. Jamar is miles ahead at the moment, which is unlucky for PJ because he showed a lot before his injury.
Not gonna start the Miller argument yet again, but there is definitely room for both he and Dunn in the side. Dunn is a baby, and his form is likely to drop. Not sure how he will handle finals either, given his body shape and the fact that he isn't overly aggressive. Miller gives us the flexibility that a Dunn-Holland combination won't.
As for the backline, very hard but I went Whelan, CJ and Wheatley. It is rare to play a team who has two excellent small forwards, and no current team who looks like a premiership threat has two. Whelan is without a doubt the number 1 small-man stopper we have, but I think Wheatley is also more than capable of doing a job on a small or a tall. I like CJ's rebounds and he is a beautiful kick, plus we need to get some games into him before Brown calls it a day. More than anything, those three are accountable, whereas Ward and Brown are very loose.
