Among others, Robinson is listed as one star that can improve his game. The major points are that he needs to work on using and reading screens since for the most part, he was a garbage man last year (crashing the boards and getting open for easy looks after Burke's drive). Also, it is mentioned that despte poor shooting from the 3-point line, Robinson has a shooting stroke that can develop into one of the Big Ten's best (making him one of the best players) thanks to Beilin being able to teach shooting like few other coaches.
This seems to be dead on to me, personally. I'd love to see Robinson take a bigger role in the offense and work on improving his shooting game.
