Mix and match bowling changes is a standard these days
That's true of course - but it's also true that precisely because it's 'standard', it's sometimes done rather unthinkingly, which is how it looked yesterday. Still, all's well that ends well.
Captains generally start off with a general plan, but has the game develops even the first delivery of the next over becomes a match up option. All bowlers must be ready now to bowl one over from either end throughout and with a bigger squad of bowlers available in the game also may not be expected to bowl their full quota.
Back in the day ends and quotas were set in stone and captains were less flexible in taking unlikely options.
Standard stuff now, it is just has much about surprise.
One thing far more certain, the day of consolidation is over and trying to keep taking wickets much more a priority, which does makes it entertaining .
