Since he made his comeback into the test squad, he has never shown good temperament as a no 3 batsman. Some teams have dashing openers like Gayle, Shewag, Tamim but no other team have a player like SN in no 3.
His last 4 test matches score including the current one.
Tamim can bat like that because he has an average over 40 batting that way. But when a batsman like SN has average of 26.80 after playing 21 test matches, it shows he lacks cricketing brain. It's more alarming that he denies to admit his fault.
