According to a Sponichi report, the NPB has until May 5, 2017 to request changes to the posting system. The current system will carry over for another year if no requests are made. No specific concerns were raised about the posting system during the NPB’s last round of meetings on April 3. No additional meetings are currently planned prior to the May 5 deadline.
I wonder if that means that Otani will remain with the Fighters for 2018.
It seems like he would present the best leverage for a more NPB-friendly deal, I would think the NPB would at least try to get something new done in that case.
