Well, alot of things happening to krob right now. Aside from USA and fans wants her to play libero. She is getting married this year. TIME is very important to her and being in europe olaying, the oressure and the demand. If you are a newly wedd you need more time. And maybe that's her priority right now. Who knows they are also planning to have baby after OG and Japanese league and it'll be less stressful for both of them.
Guys it's not all about high level or which league is the best and who's team is better. These players are all professional and been experienced alot. Playing and sacrificing alot. She doesn't need to prove anything to anyone. Any club can sign her and get big contacts but as of thr moment the most important thibg for her right now is time and future family.
