I don't want to be mean, but WIndies innings was terrible to watch.
BD were awful in the field, very mediocre with the ball and gave away 19 extras. That is the difference between a RRR of 7.55 and 8.55
And despite all this, BD did fairly well to keep it down to 171. Ofcourse, WIndies were equally poor. They are a team full of sloggers from no.1 to no.8. Any other top team would have scored 190-200 if the opposition gives them 19 extras and a bucketful of drops and misfields
BD can actually pull this off if they are sensible (LOL ??) and can tackle Narine successfully without much damage
