Who to start!!!! Zac Smith Krak or Knights

[antonc]

Sounds confusing maybe, but can move Petrie to Forward line and Krak or Knights to the bench. Zac Smith will go on and replace petrie in the ruck if I do that.
Other forwards are Buddy Volt StevieJ Fyfe Goodes Missy (also have darling on the bench)
the question is which one of these 3 will score best
Krak in a depleted pies midfield with more midfield time
Smith against Roos at home
Knights to bounce back after ave performance last week against Eagles at home

Ps only have prems in midfield so no use moving any of dpp to mids
Gablett selwood aswallow mundy boyd pendles (mzungu and hibbs as bench cover)
