See the thing is India can still win this WC
Last two group stage games should be a cakewalk. Then it's just the two KO games. In both games, if our bowling shows up, we only need about 250-280 with the bat, and that's been pretty easy for this lineup despite all it's flaws.
Chahal has had one bad game. He's bowled well so far as has Kuldeep. I can see the argument for getting Jaddu in the XI, but I don't want to go down the 'pick a bowler for his batting' route and Jaddu is already basically fielding all 50 overs anyways.
Pant/MSD as opener is interesting but they just don't have the game to survive the Aus/Eng/Pak/NZ new ball attacks. Lokesh, for his flaws, has some sort of proven track record, and I reckon we can rely on him to get us some sort of start more often than not. The 9 ball duck was his first low score of this WC, his next lowest score with a dismissal is 26 off 42. Pant and MSD are both wayyy too prone to nicking off early Vs a swinging ball.
The only change I would consider is Karthik for Kedar. If Jadhav isn't going to bowl, we may as well leave him out for a batsman who is more dynamic, probably in better touch, and who is also a much better fielder.
