U19 12th Man
Can't discount 2015 onwards. That would discount Ind's win coming from behind in 2015 SL and most importantly the 17 BGT where India showed the same come from behind qualities in all 3 matches - Winning Bangalore after conceding a huge 1st innings lead, overcoming a 400+ first innings score in Ranchi and then outbowling Australian pace bowlers on a pitch with pace and bounce in Dharamsala.I think India currently does have a certain je ne sais quoi that makes them quite a bit greater than the sum of their parts, though. On paper they should have been blown away by Australia last year too, and they honestly should probably have lost in England. But they find a way to win, somehow, and that's an intangible quality that "on paper" lineups can't quite capture.
I will make it clear again though: that's principally because of Bumrah in particular and Siraj more recently, and so the analysis from 2015 posted a few posts ago is entirely irrelevant in my eyes. As far as I'm concerned, this current Indian team was born in 2018 when Bumrah became a permanent fixture of the team.
If there is a criticism of the SA side of that era, it's that they were the opposite: they were sometimes less than the some of their parts and the otherwise stellar batting often creaked when put under real pressure; it lacked firefighters and lower-order tenacity to dig them out of holes. Which is why Australia were consistently able to take games off them at home when really SA looked the much better team on paper. That was the era when "downhill skiier" was applied to Kallis and ABdV a lot.
Even in the 16 WI series or 16 Eng series or 16 NZ series Ind were in trouble at various points but came through.
