I think you do have to explain, unfortunately, because this is pretty indigestible too. No better middle order options available as far as I can see, not even close.
He doesn't add any dimension to the batting - numbers are immaterial here. Bowling against PAK is like shooting at wall - it won't change with Fawad.
Apart from Haris & Babar (I know his Test stats), every PAK batsman (may be excluding Asad, once set) are extremely limited shot makers - they keep on scoring mostly to their few arcs - in Test matches, that results in 2.2 RR for batsmen with Azhar's temperament & average of 23 for Shan/Sami's composure or Asad's choking when under pressure. In ODI, it ends in attempt to Hollywood shots - and Afridi becomes hero, once in a blue moon.
Instead of Fawad, PAK should look for batsmen who are capable of playing shots on either feet, either direction - Fawad doesn't help that. It's a compromised call between playing players like Fakhar, Amin, Haris, Babar, Saad Ali, even Umar Akmal or may be Zeeshan (I know, his FC average is 15), Saud and expect that they'll gradually improve their batting sense, their shot selection & their defense - or I can load the stable with Azhar's clones who would give a false feeling of security - 201/4 at 2nd ball, then it ends in opps - 256 in 105'6 overs, on a 450 wicket - we have seen it too many times.
Now, PAK domestic is an inferior version of Lancashire league Div 2, and the Captains are equally matching in tactics - so players like Fawad or Manzoor or Asad (I hope, you know his List A stats), Maqsood or Ahmed can puff up their stats basically sitting on 1 or 2 trick pony - this will be badly exposed even by International U19 Captains, if they are groomed in proper system - they'll have a close look & after lunch or tea break, will come out with a restrictive tactics, eventually the inevitable down fall. It doesn't surprise me that most other teams, batsmen scores almost double in their 2nd 50 balls than first 50 - PAK batsmen actually slows down.
You can check my post this morning - Chandi changed Dilruhan next over after getting a 5for & back to back wickets, once Amir was back & Yasir joined Asad - because he wanted Yasir to go for this favorite onside cow shot against spin & he kept his mid wicket open to encourage that, and he got Yasir out exactly the way he wanted him to play - forget QEA Captains, PAK national captain won't have changed Dilruhan, because he had a 5for. Before that, he got Sarfraz out to his bread & butter shot with a 79 overs old ball - by an offie, coming into him, on a wicket hardly turning - this happens only when you can make sure that the batsman has only shot to score & that's in your channel - just cover it for ambush.
I can give you another clue - more or less every left-arm spinner is making PAK cry, but in QEA, they are bowling at dozen rate & they are bowling tight, turning as well - but, there is a little gap between what Imran Khalids has & what Rangana Herath has - that little thing rests below their skull - Fawad has better material there than what most of those in QEA has, but that's not enough to match Rangana Herath.
Those stats are absolute meaningless to me - bowling equivalent is Asad Ali, Sadaf .... ...... many, many, many who are winning FC matches in 2 Days. I watch cricket & judge batsmen from what I can see, didn't lose many bets on that.
