I'm not sure whether Azhar actually said that, and I'm also very lazy to fact check it for myself.
But I'm pretty sure that somewhere I saw some really reliable journalist or analyst say that Abid Ali was average in the first half of his career. He had a mediocre average and was very inconsistent, so how do you expect anyone to select an average batsman into the Test team, obviously not knowing that he'd get a lot better in the next five years?
I think it is very unfair to criticise someone over the 'snub' of Abid Ali in earlier parts of his career.
