Ye thora ziada ho gia hai. Hassan Nawaz hasn't been tested by a 145+ kph bowler yet. Babar was immensely talented.
Babar always struggled against pace as well even during his early days.
People keep highlighting his performances against starc and many other during his under 15 to under 19 days not realising the starc, Rabada and many others who bowled to him were no where near the level that they are at now.
Starc took the world by storm in 2014-2015 as did Steve smith since unlike Warner who was the greatest talent before debut, people viewed starc and Steve smith as just decent to good player.
No one imagined what would have occurred with one becoming one of the greatest test players of all time and the other having the greatest bowling career with 4 tournament wins, Multiple ashes wins and the greatest pink ball figures in history.
Babar during his younger years was avg 41 in FC, 55 in List A and 40 in T20 and his sr was the 2nd lowest amounts his group. Infact babar was 2nd fiddle to sami Aslam at the time who avg 50+ in both list A and fc with 100+ sr in list A. And we know what happened to sami aslam.
Babar's under 15-under 19 figures are the exact same as his international numbers ironically.
Hasan Nawaz Has raw power something babar never had.
