I've decided I want to alter nearly all of my players positions. What's best way of doing this with minimal disruption? If I start training them in positioning will they be learning where I want them to go or where computer has them at present? Should I just keep playing in my preferred positions and accept I'll struggle for a while? Am in a division with 9 bots so hopefully experimenting won't disrupt my season

Tried to find the answer to my question - couldn't, so: is it known what happens to natural role in case that one plays in Offence & Defence at the same match? As i know in case of Offence/Defence & Special Team the only last counts. Is it true?

incorrect. it depends on what position is calculated last. we only know that special teams is last as of this point. offense defense has not been detailed yet. sorry to evade with a non answer but total playing percentage has no relevance.
