Whatever I have seen, I really liked Zia.
If he is given few chances (not one chance and gone) in ODI and let him grow, I think he will surprise lot of his doubters.
I think he can play a very good role in our team where our playrs tend bat inTEST mode in ODI game. Yes he has technical weakness, but who doesn't? I see him another Nasir in that aspect, given some chances he will grow and will eventually become an overall consistent performer with "match winner" potential.
