You wouldn't do it but right now, I suspect that he's invested in Carlton because they sold him a dream and offered him the right amount of dollars for him to buy in.
Martin's manager is making all the right noises about the Carlton Dream including claiming that we can't afford him. Well, we could afford Jamie Elliott and if Martin is worth $200kpa more then that could be saved by delisting players we have yet to contract. Trading and drafting is about improving your list by getting the best available players.
If Martin can play - and I suggest that he can be good with the right coaching and in the right environment, why aren't we having a crack at selling him the dream and getting him on board?
