Potsdam is playing very fast this season. Overall he usually has his fixed starting six and makes very few changes, some players never see the court from the inside. He's a very emotional coach which at times can be good but at other times surely can be difficult to handle for some players.
Then it sounds very weird why they did not keep Gamze as setter but makes sense why they transferred Kanami Tashiro. He sounds very similar to the current coach of GS.
