It doesn't really matter how close they got since they still lost thanks to which the series comfortably went to the hosts and that is what everyone will remember at the end of the day. Pakistan messed up big time.
The division between top teams and mediocre ones keeps widening as time passes in literally every format of cricket.
Well.. that's actually surprising, because I consider Pakistan as one of the teams in the top-tier, and there is no doubt that Bangladesh doesn't belong there. And then we have two consecutive wins from Bangladesh over Pakistan. The issue here is inconsistency from Pakistan. Also, as I mentioned previously the selectors sent a second string squad, which didn't fared well. Bangladesh also had the home advantage, as the matches were played at the Sher-e-Bangla National Stadium in Mirpur.
