After calming a bit, Unadkat is the best seam all rounder we have - Indian, so either be with it or bring in another youngster - Arshad Khan or if you want a spinner, Sanjay Yadav. A very close observation - though the questions sre being asked on bowlers, its actually the batting which is struggling.
v DC - lost a match due to poor death bowling after having them 6 down for 100.
v RR - Needed 50 odd off the last 6 with 8 in hand.
v KKR - below par batting, Cummins special.
v RCB - again below par batting.
v KXIP - 33 off 3, if you can't chase that with Pollard & SKY it's really sorry.
v LSG - Poor batting at the top, left too much for the end. This could be the game where actually the bowlers lost it.
v CSK - 56/4 in 10 overs, unacceptable, but Unadkat should have defended 17.
To sum it up:
I Kishan - 191 @ 116 (140 odd in 2 games)
R Sharma - 114 @ 126
K Pollard - 96 @ 137 - for him, it's significantly below par.
D Brevis 121 @ 161 in 5 games - fiery youngster but no big innings as yet.
SK Yadav - 232 @ 154 in 5 innings
NT Varma 234 @ 140
With this rate you can't be blaming the bowlers. MI has only crossed 180 twice while chasing 190+ and 177 in the opening gane
