Will ignoring Shaw prove costly?

Prithvi Shaw scored a century on his Test debut for India.  There are very few players in India who do this. Due to this performance, Prithvi Shaw got a place in the team and he played 4 more matches, but during the Border Gavaskar Trophy in Australia, when Prithvi Shaw did not get runs from his bat, he was dropped from the team and since then he has not played in the Test team.  I could not make my place in the test.
