Actually, I don't. The Cubs are one of a hand full of teams that has the cash to be able to sign one of these type of players from Japan. I would much rather be fighting against 5 other teams for a player than the whole MLB.
I can see your reasoning there, but I still believe that all teams (even the Yankees) operate within a budget, and I think the posting system just sets up teams for gross overspending on players that have a high probability of not living up to their contracts. I'd much rather see the Cubs use the type of money that seems to be spent on these deals on accomplished veteran free agents that have already proven themselves in MLB.
If nothing else, the success rate has been pretty abysmal. Other than Suzuki and this year, Darvish, I can't think of any real great signings from the posting process. In fairness, if you asked me to name any more, it would be a very short list.
At the very least, I don't believe that we should be paying multi-million dollar deals to the Japanese league just to talk to these players. If we're going to have a silent bid for the services of the player, that's one thing. A silent bid to be able to negotiate with the player is just plain stupid. A flat fee to do so would make much more sense.
