Saori Sakoda also retired last year. She was the Neriman-like high flyer. Not as big and strong but better at defense (non-receiving-but super scrappy on floor defense, and she used to rotate into MB position because she could jump real high)
hmm I don't think that was the reason for her to rotate into MB position. after 2012，coach Manabe started his new strategy MB1 for the Japan team. so basically they only had 1 MB and an extra Opposite in their rotations. Saori Sakoda was that extra Opposite taking the position of an MB. when she was in the front row she would attack just like a normal opposite rather than an MB. this experiment lasted a few years and I don't think it was very successful based on the result of the team achieved but this sort of experimentation should be highly encouraged.
