I dont think Martin is worth 650k. But we had to offer more to convince him to leave, so there is a premium there.But you said he's worth $750k, only 100k more than Martin. One could assume based on that 2 x 2nd rounders would be fair or PSD.
Look, I dont want to be dragged into insane 'PSD OR NOTHING' debating here, or ridiculous trade proposals for 'McKay for a used condom or else'. The reality of the situation is that should he leave, it'll be for unders (something like a future 1st) and not a token 3rd rounder and a reach around behind the MCG.
If you guys want him, and are prepared to offer insane money, we'd let him walk, but for fair compensation in the ballpark of a future 1st (which is unders).
