I was a fan of Nawaz but it seemed like he reached his peak during the Asia Cup match vs India. I think its better to invest in a proper spinner, and have Shadab as your spin/all arounder, and maybe try to make room for another batsman, I think Nawaz, can still play for the test team, for the time being, but would want to try someone new for white ball cricket.
Nawaz isn't a proper spinner?
