If only guy was picked 5 years back and got couple of years under pro set-up. In fact, in 2016 tour I did write that instead of Sohail & Imran, PAK should look for younger pacers like Hasan & Abbas. Very good skills for English condition, and he is bowling close to sticks now.
An out of box thought, because I haven't seen him ever with white ball; but for a June/July WC, Abbas isn't a bad shout. Fahim & Shadab gives enough batting depth, which probably allows to play 3 specialist pacers on bowling merit; added benefit is Amir & Hasan's batting - Abbas can finish his 8-10 overs at one go with new ball, and doesn't even come back. Imran used Aquib similarly many times.
These days, every ODI batting line-up is head heavy with often a hollow at 4-5; couple of wickets with new ball in PP, is like 50 runs head start - Abbas is a risk worth taking.
