Atlanta is still in the title race contenders, their last five matches looks more appealing than that of Napoli who haven't won a single match in their last five games.
The 3 teams at the top of the table have had terrible results in the last 5 games. They have lost a lot of points, but I think Atalanta was the worst embarrassment among these 3 top teams in this last round. Napoli played against Inter, which is a strong team. It makes perfect sense that the game ended in a draw.
But Atalanta drew against Venezia, which is in the relegation zone. A team that has only won 3 of its 27 games. It was expected that Atalanta would win, but they drew. I don't see Atalanta as a team ready to win the title. Only luck would make Atalanta champions.
