Whether we like it or not, the schedule for this season simply does not allow for players to appear in all matches. Sports science tells us that and is a bit more, er, scientific than just saying the players aren’t going to get tired.
If there’s a fault, it’s that the current ODI series is a bit pointless in the context of the World Cup build up.
The comparison with Pakistan supposedly playing their best squad isn’t relevant. They have fewer players who are in both Test and ODI teams and their schedule is different from ours.
