a player out of position sucks. this is worst that can be. but, if you are short of him, for example DML, it is better to try with red dl, then put dl on his position. i tried. what sucks is the fact that you dont play in "normal" formation, that sucks. lets imagine you wanna play 3N-2dml/dmr-3N-2. when you miss your dml, and play with red dl, you do not play 3-2-3-2 but DL N N N - DMR - 3N -2. this is what is not good.
