He didn't need to chip it to mid wicket. England are nicely set, Bell and Morgan set a good platform, typical Bopara.
England's tactics of seeing off the new ball and then exploding in the latter overs will always mean they don't score as many boundaries in the first 30. Whether that's the right tactics or not is highly questionable outside of England.
If Morgan and Buttler bat to their capabilities we will get the much needed 300.
Given those tactics, the powerplay in effect and 2 batsmen to come, bopara is expected to go and play shots.
With England packing the batting and weakening the bowling line up, that tactic is wrong.
You had the top 4 struggle to get maxwell off the square, for him to bowl 8 overs for less than 4rpo is just poor
