I would prefer Napoli to win the Scudetto with a difference of 1 or 2 points from Inter Milan or Atalanta.
Inter, Atalanta, Lazio or Juventus can compete closely.
Outside of this discussion, I would like to suggest you to improve the way you post. If you quote like this, it will look like a pyramid.
It would be very interesting if they could win the title with such a difference in points, because it would certainly be a competition until the last match in Serie A. Actually, this does not only apply to Napoli, but maybe to Inter Milan, Atalanta or other teams in Serie A. When the competition is determined until the end of the competition (the last match), then it is certain that it will attract many people to watch and follow Serie A until the end. Because sometimes we see some competitions already have winners even from the last 8 weeks that are still left.
