I can only comment on the ml/ mr position.
A blue does not make him play as a dml / dmr, but a rather as a defensive ml/mr, if this makes sense. He still does go forward and he does get to score, when it suits the MoFo.
When in red, the possession seems to go up a bit, but they still seem to steamroll my midfield, dmc and dcs, with those, oh too often,periodic bursts of counters. Thankfully the GK knows where the posts are.
