Marcus Smart had a decent rookie season, averaging 7.8 points, 3.3 rebounds, 3.1 assists and 1.5 steals per game. He launched a ton of threes (more than everyone expected) but managed to keep his percentage (33.5) above what it was in college (29.5).
Smart's defense can't be quantified as accurately as his offensive production, but that side of the ball is where he really impacts basketball games. His ceiling is unknown, and it's not crazy to say Smart can be the very best defender at his position someday soon.
If his outside shot improves and he can get to the basket at will, Smart could become a legitimate two-way star.
I'm not sure if Smart will suddenly become a knock-down 3 point shooter, but as he gains more confidence with his shot and picks his spots better, I think he'll be able to keep defenses more honest. Also, if his summer league performance is any indication, he should be attacking the basket more this year, which in theory should open up more space for him to launch open shots. I think his playmaking lagged a bit last year, but that's hardly surprising for a rookie point guard. I'm very much looking forward to seeing him operate in the pick and roll with David Lee and even Amir Johnson this year. It will be interesting to see what role he plays in the offense when he shares the court with Isaiah Thomas.
