In an almost 'range hitting' match that happened today, Deepak Chahar and Keshav Maharaj turned out to be the best bowlers. Especially Deepak Chahar's figures looks brilliant though he didnt pick up a wicket. I watched the 2nd half of SA's innings live, and that one over Chahar bowled at the end (was the 17th over, I believe) was EXCEPTIONAL to the core!! He literally tied Miller and De Kock into knots. Chahar is known as a specialist Power Play bowler, but over the past few IPL seasons he has been honing his death bowling skills and one must say that he showed a very impressive display of it today!
I still feel DC can be a good fit to replace Bumrah in the T20 WC squad. Yes he is similar to Bhuvi, but why cant DC, Arshdeep and Harshal play? World Cups and especially T20 WC's should likely have batting fests. In which case, pace might not be of top most importance as variations and smarts. And Chahar beefs up the lower batting order significantly.
