After playing around with it a bit more, the only solution I've found is to play 'very fluid.'
The game's definition for very fluid states that it expects all players to contribute to all phases of the game, meaning attacking players have to be able to defend and more defensive players have to know how to get forward when needed.
It doesn't bother me too much because my playing style is set to 'attacking' and I was playing on 'fluid' anyways, so bumping it up to very fluid is fine with me. But people who play more conservatively can't really put it on very fluid because I think the game recognizes that as an attacking philosophy and it might cause your players to be somewhat confused.
