That wicket ball wasn't extraordinary but considering the pitch and Klassen's form in that particular match. Off line wide slow delivery was a nice tactic and Pandya deserves credit. Ofc no one can deny Bumrah's role in it, that's what he does in the majority of matches, build pressure from one side and allow other bowlers to take wickets from the other end.
Also, we shouldn't forget that 2-3 minute break (Due to Pant). It broke the Protea rhythm or call it a lapse in concentration, just after that Klassen fell.
True. It was a great combo effort, but most credit definitely goes to Bumrah. I haven't been impressed by any pace bowlers from the Indian squad these days excluding Bumrah and Shami.
On the other hand, they have so many great spin bowlers these days. Expected a lot more from Siraj in particular.
From the last T-20 WC point of view, there wasn't much for the pacers in the Caribbean. Seamers feasted in USA's leg tho. Almost every team, including India, went with an extra seam attack and Siraj did a decent job there. Yeah, SL's series didn't go well for him but those pitches were prepared for spinners, not seamers so I won't read much into it, in terms of seam POV.
Surely there is a big talent gap when compared to Bumrah or Shami but IMO Arshdeep and Siraj did alright in patches but need a strong bench in the seam department for sure.
