I see JVR as a backman.
I can't see JVR lasting past the first round. Too many clubs needing KPPs, and he is the 'safest' pick for mine. That is, anyone chasing a KPP would look at JVR as the best bet to make it in this crop. I think his versatility makes him a better bet than Gibcus, although Gibcus will be in high demand as the best tall defender out there.
Bazzo seems to have fallen out of favour with many. I'm suprised, because he has the attributes of your prototypical AFL KPD. Good intercept mark with good closing speed, really good decision maker and user of the football with a penetrating kick. He lacks consistency, but a few years in an good AFL program should remedy that.
Just remember the last KPD we drafted out of Swans Districts. He went all right.
I doubt Bazzo will be that good, but I reckon he will make a fair fist of things wherever he gets a chance.
