You are 100% correct with that statement. Nunes will be great in the role Pep puts him in. That's what makes Pep so special. He gets the best out of the lads.
And to your first point. Fair enough. I'm not trying to ride Rice's meat but what I will say, is pay extra attention to him in Arsenals matches this year. You will see he has no weakness. Possesses far more qualities than a traditional #6. Leader. Can invert in CB. Can play the 8. Press proof. Line breaking dribbler and passer. Top level control. Can crunch a man in the tackle. Recovery speed is also top notch. Reads the game with the best of em. He can do everything you would want if you created a number 6 at an elite level. But yeah, keep an eye on him this season and decide for yourself. He is an analytical darling for the data diggers which is what inspired me to take a deep dive into him as a player. So so good.
