You wont be able to quote many duds in international cricket who had List A average of 55 with SR of over 85 (Ofcourse exceptions might exist but, they dont make a norm). Yet to see him getting out playing a defensive shot, correct me if I am wrong. On the other hand he is not supposed to be a technical beast batting at no 5 and 6, what you want from him is that he takes the innings deep if he comes in early and to be able to hit blows during the death overs. He is no Nicholas Pooran or Ben Stokes but, can play clutch knock on his day in his style. If he have unearthed a young world class no 5, 6 who can destroy the attacks, I would be happy to see him in the team even with a List A average of 10 or 15 so its not only about numbers, I agree rather caliber. However, any one with caliber that is currently ready to take the spot?
If there is a better option then he should be playing but, suggestion of older Asif Ali (Who doesnt add much with ball as well) who has a mediocre List A record doesn't seem to be the solution. We often criticize selections and players without talking about the solutions.
