But you could still substitute a leggie for an off spinner or a left armer for a right armer, which could give a tactical advantage, depending on the match situation.You could bring in fairly strict rules that would only allow like-for-like substitutes. You wouldn’t be able to sub a spinner in for a quick bowler for example.
If I'm batting fourth, I'm having Callum Parkinson pull up in the last few overs of the third and George Drissell replace him for the fourth innings.
