Imam and Babar should both be able to get 400 runs at least. Not that hard given that we play weaker teams as well, and these two will have a few decent scores against the big boys as well.
Haris will score around 450.
Betting on Fakhar is hard here because teams take world cups seriously, they will tactically bowl against Fakhar and exploit his glaring weakness, speaking of which, did he alter it in the PSL? If bowlers get under pressure and go off from the plan then Fakhar will give us those valuable quick starts, he will have a sub 30 average.
The only batsmen who put a price on their wicket in the team is Babar, Imam, and Harris, and they will be the ones to score the most runs.
