Shaheen Shah is nowhere close to Wasim Akram
But Pat Cummins, Bumrah, Mitchell Starc, Anderson, Trent Boult are at the same level if not better than the likes of Wasim, Walsh, McGrath, Ambrose
ALso Jeff Thomspon never bowled 161 kph or Andy Roberts never bowled 159 kph during a match, It was hyped up tv show with dodgy technologies. Plus forget 70s, even 20 years back speed guns were very dodgy. During 1999 World Cup geoff ALlot was clocked at 145 kph and he was typical medium pacer
Yes Cruyff & Beckenbauer wud be the best if they play today - but they wont be playing like they were in the 70s. They wont be partying all night, wud e more disciplined, spending more time in gym. Cruyff spend whole nights during 1974 World Cup partying & drinking in a hotel pool. Can u imagine doing such stuff now ?
Fred Trueman bowled at about 135-140 kph. Without endless travel & foreign tours of present day cricket. Without spending half the year living out of a hotel room - away from home & family. Not apples & oranges.
Regarding tennis - John McEnroe was unbeatable in 1984 but from 1985 onwards never won a Grand Slam again once Boris Becker ushered in new era of power tennis.
Talking techniques, modern day batter don't get to pad away spinners, don't get same level of benefit-of-doubt due to DRS, don't get friendly umpires. Also batter face far greater scrutiny due to endless data analytics
