Statistically, one can't drop Fawad - in a pathetic PAK batting line up, at one point, he had an average of 47+ & SR of 75+, after 50+ matches; besides, he is easily the best fielder in the team, can bowl few overs & he was a left-hander in middle order; not sure when PAK had a left-hander in middle order in LO, for that the THICK Tank has no idea how irritating it could be when the fielding Captain is forced to change 4 men after every single, clock ticking fast & his bowlers are changing line/side 2/3 times in an over. Akalmands learn it from observation - PAK tank was THICK enough not to learn it after suffering several times at the hand of UV/Raina-Virat/MS; Sanga-Mahela/Dilshan, Tamim-Mushfiq partnership & being bunnied by Herath with 1 to 11 right-handers.
Problem for Fawad was that he was 3rd/4th in the packing order in a PAK team, where whose who mattered. In an ODI team, you can't fit in Misbah, Shehzad, Malik & Fawad - ideally 1, at best 2 can be fit in to that line up; but Fawad was at per with Asad in terms of lobby, way behind Shehzad & later Malik/Sarfraz, while Misbah was the Captain. Unfortunately, now Misbah is gone & his successor is 75% of Misbah & the next Captain. Fawad was never a player who can blast out; in fact, he was a limited player, whom professional teams could workout, but still, won't have been too odd in a PAK side that has dropped to 9th spot in a game seriously played by 5/6 countries now days.
I think, Fawad's biggest stumbling block was Ahmed - PCB's selectors were stuck in 1971, when ENG opened 1st ODI with Amiss & Boycott - that's you have to be an opener to open in ODI, and Ahmed indeed was the best option available. May be not now, as PAK should look forward, but similar time, 2 years back; PAK easily could have slotted Fawad in this batting line-up, had the vision was there - Umar, MoHa, Haris, Misbah, Fawad, Maqsood, Sarfraz ......... you can exchange spots between Misbah/Fawad, Sarfraz/Umar. Fawad basically lost to the Afridi lobby for Ahmed.
