Sarfraz Ahmed looks the most out of place Pakistani cricketer in T20I team. But his replacement Mohammad Rizwan is even worst than him.
How about selecting Umar Akmal to be a WK only in T20Is? Umar Akmal's wicket keeping is not as bad to not survive only 20 overs. Plus Pakistan get a huge upgrade on a T20 batsman without needing to sacrifice other good T20 batsmen in the squad. Always remember T20 is a pyjama cricket so you can experiment easily.
