The thing is, who doesn't have a minor injury at this level of volleyball? the players just overcome it if the tournament is important enough. That is why this reason for not having the A-team is very funny to me.
Also if this was the WCh or OG, Jenny's health issues would not stop her.
VNL is not important to China, no ranking points or any other qualification except winning for prize money. Serbia just skipped this tournament to focus on what's important for them. Nothing to speculate about. Lang Ping will not coach beyond this Olympic cycle. She is giving An Jiajie, supposed successor, more chances to coach. She has always use WGP finals for B team to gain experience and also as tryouts to fill the roster. Because China businesses try to milk on their success, buying the rights to host, which forced Lang Ping to play A team the last two years, changing her plans entirely. But due to failure to win WCH, Lang Ping is going back to her old plans, even turning down interviews from CCTV because they were a big media distraction. The Chinese fans who are complaining are the bandwagon fans who only cares if CNT is winning and watching Zhu play.
