the only thing I would say is that looking at milwoods guy, he ran a zone, meaning guys get tired slower so if makes sense to have a guy backup multiple positions to get him as many minutes possible. but it looks like you run a man. and so all it will mean is that the player backing up multiple positions which just come in the first time someone gets tired, and then when someone else needs to come out and the 2nd option is already in the game, the 3rd player on the depth chart goes in anyways. But you could try it and see what happens.
