In this run there are basically two Indian sides.
The 2015-19 run's primary architects were Kohli, Pujara, Rahane, Vijay, Shami, Ashwin, Jadeja, Ishant with support from Umesh, Dhawan, Bhuvi, KLR etc. Rohit was playing but he was crap.
Most of these guys debuted after the old guard of SRT, Dravid, Zaheer, Sehwag, Harbhajan generation retired in the early 2010s. Their baptism of fire was the 13-14 year where India played SA, NZ, Eng and Aus away.
The post Covid era 's primary architects are Bumrah, Pant, Siraj, Iyer, Axar with support from Kuldeep, Gill, Shardul, Sundar etc along with Ashwin, Jadeja, Shami, KL Rahul from the old guard who are still good and Rohit who revived his career in 2019. The others in the first wave are retired/dropped due to loss of form/age (though they had some contributions in the post covid era). Most of these guys debuted in the late 10s, early 20s (and it can be said that Rohit also made his second "debut" in 2019).
So post Covid India has been in transition. It's just that this transition was not as sudden as the one in 11 (when the entire old team started to suck after being very good from 07-11. Maybe the World Cup win doused all their fire).
In the 2013 SA series India had a completely new batting lineup with only Pujara/Dhoni being there from 2010 (no Sehwag, Gambhir, SRT, Dravid, Laxman). At least this time around Pujara/Rahane contributed a bit in their lean years (as has Kohli).
This Eng series might have shown the core that will be in place until the next transition starts.
