Is Nag not confident on Mr. Majnu?

We cannot believe that Ram Charan and Akhil will not go to their star fathers for advice after listening to a story. Even if they want to do the movie badly, they would like to take the advise of the veterans for bettering the project.

Ram Charan always agreed that Chiranjeevi listens to each and every story of his films. While, Akhil decided to try on his own in his first film with Nag just giving him few suggestions.

Later, Akhil decided to completely submit to Nagarjuna for Hello. As we that movie failed, Akhil took few months to announce his next and at Mr. Majnu pre-release event he said that Nag followed the progress of the movie and gave suggestions.

But Nag did not talk about the movie like he usually does. He said, "Vasthunnam ... Koduthunnam (We are coming ... We will deliver)" for most of his films after Soggade Chinni Nayana.

For Hello, also he did the same but the movie becoming a flop seems to have made him not talk about the film in same tone and even Akhil did not talk about film in the same vein.

Are they not confident enough or did they wanted to not make huge promises before release due to prior experiences?!
