I didn't see that (actually not watching), but the point is, now we are in an ODI era when you have to target bowlers through out the course of 50 overs. Playing safe isn't an option any more, because 270 sort of total is bare minimum that you can even think of defending. He might have played a poor shot and got away with, but - first, you have to take chances these days for 300+ totals, second, among available options, he has by far the best probability to attempt that and succeed, even once in 4 times is acceptable, if he can score a 50 ball 50 between overs No. 11-35. Batting conditions are such these days that many, many players can score a 70 ball 50 .... those 20 extra balls are the difference between 270 & 300.
