It is a probability but I think most of them have played too much cricket this year and need some rest. Also, it is good that new players have been given a chance in this match. If they are able to play well then it will prove that they can play in different formats without any issue. Shreyas Iyer and Shubham Gill need to prove themselves this time.
IPL is adding two more teams which means we will have more matches in already heavy schedule ipl. I don't think players are going to have some rest in T20 leagues dominated year. India has done right thing by giving rest to king kohli in T20 series and first test against NZ. Lyer n Gill on day one have performed well.
