So yeah, digging into the numbers I’ve found only two sides that have bettered KKR’s points total this season in a fourteen game season. These were Rajasthan Royals from 2008 and Kings XI Punjab in 2014. There have been a few sides that have equalled KKR’s points tally.
However, none of them have got the mammoth NRR that KKR does. In fact, I remember seeing only a couple of sides with a NRR of above one when I had a quick glance (one of which was MI). And KKR has a notably higher NRR than MI anyway. You could even argue that KKR were unlucky to have had two washed out games from which they could have got four points instead of the two they eventually did given that one was against a listless GT outfit and another was against RR after they had lost Buttler and Hetmyer.
A matchup between 2019-20 Mumbai Indians and this version of KKR would be a sight to see.
