It is quite obvious there isn't one. I don't think Amir has that kind of personality, Devin does somewhat but he doesn't create offense, he just scores.
Call me crazy but Jerome Derosiers seems to have the most spirit on this team(not saying it translates to leadership right now but I can foresee him taking on that roll at some point).
Our biggest hope is that our new pg acts like a pg and leads next year.
