I don't know. With an open auction, you wouldn't have the high bid be $30M and the next highest be $10M as abuck described. True. But, you also won't have back and forth bidding that could elevate the bid way beyond 30m. For example, if Boston doesn't want the Yankees to win the bid, they could up the bid everytime the Yankees have the top offer. If nothing else, teams could force other teams to way overpay, which in turn hurts their chances of improving elsewhere. If the Yankees had the top offer of 30m, Boston could bid 31m, Yankees go to 32m, etc.... As successful as a lot of these Japanese players have been, it would seem like a win/win situation for the teams in Japan to have an open auction.
