Don't be fooled by KW's average as that query is very general.
Here's a much more telling stat for me.
If we can all agree that since 2000 the best 5 tests sides have been Australia, England, South Africa, India & Pakistan (in no order), this is where Root & Smith really show their worth, with Kohli not far behind.
In fact Root & Smith have the best records against top quality opposition of all batsmen since 2000s, both averaging over 55. Meanwhile, against top opposition Kohli averages 51 & KW way down below 40.
In KW's case, he generally relies on murdering relatively weak Windies and SL attacks, and he did admittedly do well on some roads in Australia in 2015.(Not so well in the more difficult deck in the Adelaide Test though).
This bothers me too
The bowling and conditions England faced in BD were extremely challenging and they should be credited for all the runs they scored there
The Adelaide Test was tough for all batsmen involved. 20 wickets fell with only 3 batsmen crossing 50 and a highest score of 66. KW got two good deliveries. To even hint that this shows his failing as a batsman is ridiculous.
Any attempt to look at a batsman scoring runs and saying 'Well yea but those conditions were easy' strikes me as being so disingenuous. It as though it's not possible for the batsman to
make it look it easy simply by being so good. It's ignoring the fact that he faced tough spells of bowling in order to still be other there when the bowlers got tired/conditions got easier so he could score big. Kohli weathered tons of tough spells in India just now from England. The 40-odd in the 4th innings in the draw was sheer skill, and he survived several spells from England's quicks and Adil Rashid. But the narrative has now become him capitalizing on ****** bowling and dropped catches. Yes he did that,
but he also survived really tough scenarios, and thus was able to cash in when it got easier.
All of this analysis by statistics stuff is just being done so badly. Judging how good the bowlers are based on career records and not how they bowled. Judging how tough conditions were based on end scorecards and, again, not observing what happened. Acting as though teams that lose a lot never put up a challenge. Not giving players credit for doing well, but focusing on when they failed.
It seems the only performances that 'matter' under this means of analysis is when one batsman scores an extremely high % of the runs scored in an innings, or when on bowled returns crazy good figures in comparison to his teammates. And even that's ridiculous sometimes. Rahul's 199 doesn't become less of an innings because Nair scored a 300. Jadeja taking a 7-fer in the 4 innings doesn't mean he bowled so much better than the wicketless Ashwin did.
This is such lazy analysis and I expect a lot better from CWers tbh.
