India needs to have format specific players now. The likes of Sarfaraz and Shaw, in this form are simply too good to be left out. The selectors need to make a wise (and perhaps hard) decision in terms of what their best XI is going to look like for each format. The abundance of talent+IPL means that every one feels they can be a part of each and every format. Given the amount of cricket being played by India, this is something that should be factored in.
From a coaching perspective, even Dravid ought to let go of some formats. I have said this before- it makes sense for Dravid to act as the Director of Cricket wherein all national teams(Men, Women, U-19) ,their coaches(assuming we go format specific) and the NCA Head report into him. India could truly benefit here if they go for format specific specialist coaches.
