Harvey Trade (390k to play with)(very weak backline)

[Kyuss]

hey another that needs to get rid of harvey
will give me 390k to trade with

Thinking either Ziebell(leaves 150K), krakouer(leaves 90K) or warren(leaves 300K).

Want to make a saving to strengthen backline, which is weak as.
Have jamison doing f all at 150k and looks like heading lower.
Already got a lot of rooks (Hill, Rance, Petrenko, Cheney,N Brown)

thinking about getting Gilbert(300K) but would leave virtually nothing to spare(with ziebell),
has he peaked?

Also considering Mcpharlin whos lost 50k to 265k
want to slip in either Raines, Grimes or Hurley next round perhaps Greenwood as well.
or should i slip one of these guys in for this round.

Leaning towards Warren as certain to gain, can get Gilbert then get Grimes or Raines next round?
Grimes v Raines? prob raines

Any help would be appreciated for a DT rookie,
Thanks

Adjusted plan:
thinking Ziebell in for Harvey,
Ryder in for Jamison.

Round 6 trades:
Cheney, Petrenko/N Brown for
Raines and Hurley

Will Ryder play out the season as the bombers main ruckman?
