re: Yousuf becomes No. 1 Test batsman => slips to no.5 => Gambhir new no.1 test batsman
Yousuf is just made from a different mold of heroes than Imran or Javed. Some people do their own part and heroes do their part and the part of two or three others. Kamran Abbasi is looking for a captainacy/batting coach/on-pitch counselor role from Yousuf.
Instead of having Yousuf become a motivational speaker for other batsmen, maybe someone like Asim Kamal, Mohd Waseem, or (very unpopular) Fawad Alam as an insurance against collapses.
Nobody ever mentions Moin Khan when talking about the 92 semi, he was the one who pushed us over the hump at the end.
