I am very disappointed with Bangalore's performance. They can't win against LSG either. After an impressive win in the first match, they lost the next two matches. The Bengaluru team was also defeated by 81 runs against Kolkata. And in the last match, too LSG batsmen scored 213 runs against Bengaluru bowlers. Bangalore's bowlers scored more than 200 runs in both matches. The Bengaluru team lost due to not getting good performance from the bowlers. Bengaluru should focus more on the performance of their bowlers. Because if the bowlers perform so poorly, Bengaluru's overall performance will not improve in the upcoming matches either.
All their fans are disappointed for sure, and you are totally right that their bowling attack is way too poor this season. Wayne Parnell and David Willy are not proving to be enough to provide some fearful attack for their side and defend targets that are not meant to be chased down. They will definitely need to consider other players instead in upcoming matches.
Their batting was poor in the last match but they made a pretty good comeback this time scoring 213 runs, they lost only because they couldn't manage to get wickets of destructive batsmen like Stoinis and Pooran on time. If they could manage to get their wickets with a good bowling attack, they could easily win.
Warner could have asked Anrich Nortje to bowl the 19th over instead of Mustafizur Rahman. Nortje was the best bowler for DC during yesterday's match and his decision to give 19th over to Mustafizur backfired when the Bangladeshi pacer conceded 15 runs.
Mustafizur Rahman has been bowling 19th over in IPL for years since he was playing for Sunrisers Hyderabad. So, he must be one of the specialist in death bowling and in yesterday match also, he was good for first 4 balls of 19th over but last 2 balls were hit for sixes which helped MI to need only 5 runs in the last over still Anrich Nortje showed his class and he almost pulled it but lack of support from fielders (Mukesh Kumar dropped a catch and improper throw) led him to concede required runs.
