Besides Wahab, when was the last time Amir and Hassan bowled an entire over at 145+. Genuinely asking as they both seem to hover around the 140 mark with the occasional one hitting 145
Don't look too far, just check out Amir's speeds in his last two International Matches. Hasan was also quite quick in the same series but was quicker in the BPL.
As far as the youngsters are concerned, in the semi-final of the u19 WC Musa, who was regarded as the slowest out of the Pace Trio against Aus series one month prior, was racking up speeds up to 147 in his second spell (speeds weren't registering until midway of the first innings) and was as fast Nagrkhoti in that match. Shaheen and Arshad (visibly discomforted in the match) were easily livelier in the previous matches. I don't think we should give weight to too many of these speeds in u19 WC because the guns, as I initially suspected, were probably overclocked. In what world were Musa and Nagarkhoti bowling as quick as or quicker than a Rabada, Cummins or Starc, operating in the range 142-148 kph? I highly doubt that all of a sudden, in a space of two years we went from one 140+ bowler in the whole u19 WC tournament to at least one in each team participating in the cup. The discrepancy is too large to discount on just coincidence or on NZ's bowling conditions.
Apart from that, all I keep hearing is that India has 10 or so bowlers operating at above 145. I highly doubt that. The fastest bowl bowled by an Indian International bowler in the previous year was 148 kph by Bumrah (according to BCCI). Even Amir has racked up to that speed a few times in the t10, t20 series vs NZ and the last t20 vs Sri Lanka. It's quite mind-boggling that India had 10 145+ bowlers at their disposal and yet sent only two for training in a series where Fast Bowling reaches its epitome i.e. South Africa. That number might be true, but I choose remain circumspect until some measurable evidence is produced. The bowlers are most probably in the range of 140-145, which is also quite exciting but Pakistan also has hands on quite a few youngsters in that range: The u19 trio, Sameen Gul, Zia ul Haq, Mohammad Hasnain, Haris Rauf, Shaoor Ahmed (6ft8), Salman Irshad just to name a few.
Is it just the media attention or is India actually improving its Pace Battery in Exponential Surges? Only time will tell. But one thing is for sure, exciting times ahead.
