Position: Point guard
School: North Carolina
Weight: 198 pounds
Achievements: 2012 Bob Cousy  Award (nation’s top point guard), 2012 All-America third team (AP), 2012 All-ACC second team, 2011 All-ACC third team, 2011 first-team Freshman All-America (Sporting News)

What he brings: Marshall, who leaves UNC after his sophomore season, is a taller point guard, and his height allows him to see the floor more easily. Add that height to his supreme offensive awareness and you have a point guard who can really control his team. He is a phenomenal passer who has great timing and a solid amount of creativity without turning the ball over often. Marshall handles the ball well and can penetrate and kick out with the best of them.
Despite having great offensive awareness, Marshall struggles to create for himself and is not a scorer at all. Because he is slow-footed, Marshall isn’t a great defender and doesn’t have much of a defensive ceiling despite his size.
Marshall’s high basketball IQ will be very attractive to teams looking for a point guard to simply run an offense, but his lack of foot speed will force him to adjust immediately in the faster NBA game.
Where the Celtics could get him: It seems unlikely the C’s would tab Marshall, considering they already have Rajon Rondo  and Avery Bradley . Marshall also is regarded as a top-20 pick, so he’d need to slide a little for the C’s to have a shot at him.
Notes: Marshall fractured his wrist falling to the floor in a win over Creighton in the NCAA  tournament and missed the Tar Heels ‘ last two tournament games. Two months later, it was determined that he also fractured his elbow on the same play. … Marshall handed out 351 assists last season, setting the ACC single-season record.
