Smart is top ten in assists (7.4/game), and among players averaging 30 mins+ per game - rough proxy for starters - he’s excellent in assist/turnover ratio (6th). Middle of the pack for assist %age (19th).
Net, he takes care of the ball, sets up a good number of buckets, but they don’t rely on him as much as some other teams rely on their guards because the Cs have really good iso players and secondary ballhandlers. He picks his spots.
