After the dismal failures of our young guns, now I really think that Afridi should be brought in, not necessarily as an opener but a later order batsman.
Salman should be persisted with for atleast 2 more series. Imran should be thrashed and sent back home. Yasir will likely stay in the team for now. May be we really need to try Asim Kamal as the keeper after a no show from Kamran, I don't think it'll hurt at all. Sami finally got injured phew to be replaced otherwise PCB does not really like to drop him no matter what, may be we should try Asif in his place (we already tried medium pacer Khalil)
Inzi may still stay away from 3rd test to hopefully recover for VB series.
Razzaq should be replaced with Rana, Malik (not necessarily due to his performance, but injury as well) with Afridi as both have fighting spirit.
