The best thing about Rockliff? Unlike Fyfe or Martin (or maybe even Pittard), there is no way Brisbane will match the FA bid. An offer sufficient to get him should be triggering a round 1 compo, which for them will be pick #2 or #3.
Given clearances are one of our issues, being a clearance king is a pretty big plus. He also provides link up play, and has shown in the past he's pretty good in the forward line. I suspect the only reason he's never done much outside is, well, why would you with Brisbane's midfield?
He comes a hell of a lot cheaper than Kelly.
Interestingly, there is exactly five years gap between the two. Are five good seasons of football worth two first round draft picks?
Rockliff is pretty handy forward, so if we want to rotate Walla and Raz through the midfield he can do stints up there. Midfields are 8-10 deep nowadays.
