I've said before Cerra's value is largely weighted by the fact he went pick 5 a few years ago (and media hype, see Saad: pick 8 as an example).
I can see us trading into the later parts of this years 1st round, and also trading our future 1st to him.
I don't think at this point he's 'worth that', but if we win the flag it'll be seen almost like a free hit in a sense.
And if we lose the grandfinal, it'll be viewed as the missing piece rightly or wrongly - only place Dogs have us is in midfield depth (rucks excluded). Both pretty strong motivating factors whichever way the game goes.
