I think its a combination of things. Meritorious cricket must be played in all situations. Resilience and intent is important. When chasing 370, 283 was at least somewhat of a response but we really should kick ourselves for not posting 300-320. it didn't require any "out of skin" performance, just simple and meticulous play would have seen a 300+ score.
balls need to be played on merit and need to be played according to situation (match/series/tourney). just because you are chasing 160 doesn't mean you crawl at 4 an over even when the bowlers give you hit me balls. at the same time, chasing 350+ targets doesn't mean u have to hit every ball to the fence.
but intent and application of the most risk-free implementation of that intent is what is ultimately important. it will maximize wins, and minimize the margins in lost games.
Cricket cannot live with the mistaken belief that people want to see big hits. People like to see goals, but no one is talking of moving the goalposts a metre wider either side. (Harsha Bhogle)
