@abhi_jacko tagging you also, since you were also in the discussion.
For me, first and foremost, the ICC rankings can go to hell. Anyone with any cricketing sense or knowledge will tell you this.For example, Pakistan is currently the number 1 ranked T20 side but they're not a better side than England, India, Australia or West Indies (full strength) in the format. Hell, I think NZ will also challenge them at places.
Now, coming to this current India side and let us compare that to the generation before. In the 2000's the Australian team was regarded to be on par with the great WI side of yesteryear. Whenever a discussion on the greatest team ever pops up, I shy away from the comparison to the WI side because I never saw them. In my lifetime of watching cricket (1992-date) that Aussie side is the best team I have seen. A side that comes close? The current Indian lot definitely has the talent to match that side. The ODI series cited by you Sai is not something we have not accomplished before. If you take out the 2007 World Cup which was a culmination of the managerial disaster that plagues us now as well, we were always a serious white ball side since that Natwest final. I keep saying, the hoopla is around Kohli but it is our
bowling that makes us such a serious threat in the shorter formats. Let's come to tests-
South Africa? Weakest SA side for me since 1992. Dropping Bhuvneshwar Kumar in the second test basically meant we were knocked out of that series before a ball was bowled in that second test.
Tactical Blunder
This tour was also the beginning of the decline of Ajinkya Rahane as he was dropped in favour of Rohit Sharma in test matches. It has now been admitted by the management that Rohit's white ball form against Sri Lanka was the reason this call was made. Rahane, who has centuries in
ALL SENA countries. Jinks was later hilariously our number 4 for the ODI's.
We won the last test which was the most difficult of all the tracks, but the series was gone by then!
England? Weakest ENG team by far as well with a very unsettled line up. WI have won there very recently, and while they have improved themselves, I don't think the Strauss/Vaughan led sides were lesser sides than the one led by Root. The captaincy around the time Sam Curran came into bat will not be on any score card but those that have seen will tell you were the worst bits in their time watching cricket.
Tactical blunder
This was also the time Cheteshwar Pujara got dropped and then at a track where perhaps no spinner should have played, we played two.
Australia? Less said the better. They were a one legged side and without Pujara, even this would have slipped out. We still won, so kudos but it is not comparable to our triumph in 83/11 at World Cup. Hell, our performance under Ganguly against the Steve Waugh side where we almost pulled off the series win against a GUN side will remain our best performance!
All in all, we can safely say that Kohli's biggest contribution to India as captain has been promoting a pool of match winning quicks. He should be given a lot of credit for that along with Dhoni. The decision to have Bumrah in tests was a true master stroke so credit where credit is due.
But, the rigorous chop and change and whimsical selections finally took their toll at the World Cup and it seems like it's going to continue for a while longer.
