The FUT draft seems rather limiting, you only have a set of players to pick from, but I was able to put together a mostly Spanish team which ended up in good chemistry. I guess you can do it that way so your AI teammates can play well with you until you get better players. That was one of the things that bugged me in FIFA 14 and FIFA 15 FUT early on having a bunch of mixed players with < 50 chemistry and having incredibly inaccurate passes, kicks that go a mile wide of the net, and defenders just standing there like a stone on the ground, etc.
Makes me wonder if everyone gets the same set of players in the FUT draft to pick from or is it completely random, I should watch some streams to find out.
