I was looking at the test bowling averages for Indian bowlers:
Jasprit Bumrah: 19.42
Mohammed Siraj: 30.87
Prasidh Krishna: 26.00
Mohammed Shami: 27.71
Shardul Thakur: 28.38
Ravindra Jadeja: 24.10
Ravichandran Ashwin: 24.00
Washington Sundar: 25.20
Mukesh Kumar: 25.57
Out of these bowlers, Siraj is the only one with a >30 average. I am not sure how he is able to find an automatic spot in the playing XI every time. Perhaps close relations with Kohli and Rohit helps.
That's some interesting stats, thanks for that.
But not squads are picked entire based on numbers it depends on lot of factors such as where they bowled better based on that Siraj was an obvious choice but giving him the long run of 5 matches is a crime though.
Indian team needs a complete overhaul for the red ball cricket or the humiliation is gonna continue. Many experts pointed out why Arshdeep wasn't part of this series, he could have been a better in terms of supporting with new ball that might reduced a lot of dependency on Bumrah alone for taking early wickets.
