Ehsan bhai, I don’t think it works both ways and so I don’t agree with you.
It is just like saying that a bowler is bowling pathetically for his side but from time to time he manages to play some match saving innings for his side. The bowler is primarily recruited in the side to take wickets and his primary role is not to score runs. If he is able to bat well then he should compete for a place in the side as a batsman but must leave his spot as a bowler.
