As already said, I am not writing us off at this point. I said months ago we wouldn't win the league.
It is an observable fact that Rice's qualities are different to Partey's. There is no logical leap to suggest that having a new midfield of different players has changed our style of play. It would be rather odd if it hadn't. You may feel that Rice and Partey are on a similar level in terms of their passing range but I don't. You should also consider Havertz and Xhaka here. Xhaka used to take the ball near his own box, under pressure. Not sure I can recall Havertz doing that at any stage.
You seem to be suggesting that we are more conservative because our opponents are most conservative towards us. I am not sure that even makes sense. It also doesn't explain how we are more conservative. You've dismissed my explanation. What is yours?
