This could very well be true.
I don't see that many owners willing to throw 50M+ for a posting fee, then another 50M+ on a contract. Just about every team has cut payroll, or maintaind it. And if the posting goes that high, very few teams will be involved.
Besides from what i've read, Yu has upside, but he's not Dice-K. If maybe it was closer to what the posting was for Igawa, 25M(somewhere around there), then a contract, I could see more teams being involved.
