A fit and in-form Haris Sohail is comfortably Pakistan's second most best ODI batsmen. However, a fit Haris Sohail is possibly a thing of the the past.
I believe his fitness is mainly a medical impediment, i.e. his surgically repaired knee. This stops him from training with any prolonged intensity, it seems. It shows in his inability to play long innings at the highest level, take quick singles and play with intensity. There *may* also be a lack of effort on his part, to make behavioural changes that will make hime more fit.
I'd like to see Haris actually commit to said behavioural changes, lose weight like Sarfraz did, to lessen the stress on his dodgy knee. This will demonstrate to the selectors about his seriousness in wanting to represent Pakistan and be the best version of himself.
This whole, "selection based on reputation" approach needs to get binned. It's the reason why we persisted with 5 years of Asad Shafiq whilst wasting Fawad Alam's prime years. Once Haris demonstrates better fitness and appreciable work against the short ball, he's welcomed back.
