Brisbane's KPP stocks I've long found frustrating. All the established key position players I consider key defenders. Andrews, Hipwood, Walker, Adams, Gardner, McStay. The developing Ballenden. I don't love any of them as key forwards.
Bailey is worth persisting with and has the scope to develop. I'd like to see him develop into some kind of rotational fwd/mid or mid/fwd.
Ah Chee I don't rate. He hasn't done enough to convince me he is worth using up a senior list position on. Four years in, not only has he not improved meaningfully but I'm not seeing a position where I feel he's AFL standard. Forward, back. There isn't a club in the competition I'm looking at and thinking he's best 22 on.
Zac has plenty of scope for development and they love him at the Lions. However, I fear he may always be a terrible kick Dangerfield style. Technique is ok but just never hits the ball cleanly. Luckily in this league it doesn't seem to matter how well you kick it as long as you get it heaps.
