This is the first time since the core of Kohli, Pujara, Rahane, Ash, Shami, Ishant and Jadeja was solidified under Shastri that I've felt like we're truly seeing what a future side could be built around.
We had a little glimpse in the '21 BG where Siraj, Gill and Pant really stood up but we knew many of the others wouldn't make it to the side again in the long term. Then there were some false dawns like Agarwal, Shaw, Vihari, Iyer etc, but this series has brought us a number of noobs that I think are far more likely to add on to Siraj, Gill and Pant to form a strong core. Jaiswal, Kuldeep, Jurel, Sarfaraz and to a lesser extent Akash Deep and Padikkal all seem quite promising.
Maybe the transition period won't be so bad after all.
