Which Defender/Ruck Combo

[Harry_West]

Hey I have limited trades and around 30k in the bank.

Want to trade Shaw and upgrade Smith (ruck)

Def: Deledio, Gibbs, Goddard, Broughton, Suckling, Shaw, Adcock

Ruck: Cox, Smith

I was thinking my options were:

Shaw - Fisher, Smith - Mumford

Shaw - Fisher/Waters, Smith - McEvoy + Downgrade

Opinions? This week or next, and which trade?
