He has always been a difficult bowler to get away and since his return has been pretty economical in National T20 cup.With the departure of hafeez we don't have someone who can choke the batsmen (Imad has been excellent in T20s but in ODIs batters have been able to play him at more than 5 runs an over and he is pretty predictable and mediocre).Raza hasan was an exceptional talent and I think we need a bowler like him to play with shadab,Amir and Hasan.As far as batting is concerned he can also bat a bit like modern tail enders
