It's not only about the training, but then BB must change the game shape system too if we would have 1 match in every 2 days, at least for playoffs. 3-4 games in a week would mean that starting roster should be able to play 120-160 minutes in a week. I think that the only option then would be to reset the game shape for playoffs. However, that would mean that teams can't get any advantage (or disadvantage) for managing the game shape and it would make possible upsets really difficult as one key factor would be taken away.
