The following is his profile from 2006 on Draft Express:
Strengths
Belinelli's physical tools are very good, especially at the European level. At 6-5 he has decent size for an NBA shooting guard, especially considering his athleticism and long arms which allow him to play bigger than his height. His overall bulk has improved over the past few years, as now both his upper and lower body strength are more solid than they were a couple of years ago. He looks like he’ll be able to add some more pounds too. Belinelli's athleticism is excellent for Europe and would be considered good even in the NBA, as he runs the floor well, has good overall speed and quickness and is an explosive leaper.
Offensively, Belinelli already has many of the skills required to play shooting guard in the NBA. He's a solid ball-handler who can dribble with either hand, usually playing under control, and is able to go right or left equally well. His passing ability is decent, as he shows no selfishness and seems to have good court vision. A couple of years ago he was projected as a PG, and although he's developed quite a bit more towards the shooting guard position, he can handle spot minutes at the point when needed.
Belinelli's biggest asset on the offensive end, especially as far as the NBA is concerned is definitely his outside shot. Every facet of it has improved dramatically over the past two years. He specifically worked on this part of his game and has become more and more consistent. He's especially good as a set shooter thanks to his quick release, compensating for the fact that his feet barely leave the ground (a la Brent Barry). He has amazing accuracy and range, out to well beyond the NBA 3-point line. When trying a jumper off the dribble he uses his athleticism to elevate and shoot over the defender, often going for a fade-away jumpshot. He moves well without the ball, and his shot selection is decent; not being afraid to shoot when opportunity strikes or his team needs him to, but also not forcing up too many shots.
Defensively, Belinelli is much more solid than many of the other young European prospects. In fact, in the past two seasons he was primarily used as a defensive specialist by his coach, as he can effectively guard multiple positions in Europe. He has good footwork and lateral quickness, which along with his length and quick hands in the passing lanes make him a great asset in pressure defense situations. He usually guards the opponents' best backcourt player. Climamio plays both man to man and zone, and his effectiveness is quite the same.
Generally, for a guy who's not even 20 years old, he shows good maturity when he's on the court, being known as a coachable player with a good work ethic. Climamio's coach Jasmin Repesa is known for his ability to develop young players, and was not afraid to give him meaningful minutes ever since Belinelli was 17 years old.
He already showed that he's a clutch player, as he's not afraid of taking big shots in the crucial moments, being a factor in his team's triumph in the past Italian League playoff Finals. The experience he has garnered playing at the highest level of competition to be found outside of the NBA is something that must be considered a huge plus; as Belinelli more than holds his own in the very tough Euroleague and Italian league.
Weaknesses
Even if Belinelli's body has vastly improved over the past few years, he will still need to add some bulk to play in the NBA. Particularly, he needs some more upper body strength.
Offensively, right now the main concern about him is his slashing ability. Although he theoretically has all the tools to be a great slasher (at the European level at least), being quick with a nice first step, possessing good ball-handling skills and improved body strength, he prefers to rely almost strictly on his perimeter shot instead of mixing up his game by taking his opponent off the dribble and going strong to the hoop. He seems to rely too much on his jumper, and does not get to the free throw nearly as much as he could considering his athletic gifts. He could use some improvements in his shot too, as he sometimes tends to unnecessarily go off balance when shooting off the dribble or off screens.
Even though his ball handling and passing skills look decent, right now they don't seem to be enough for him to consistently play the point as he was projected earlier in his career, especially in the NBA. He doesn't protect the ball well enough and still has difficulties against full court pressure. Plus, it seems that this project has been momentarily dropped, as his team is developing him primarily as a shooting guard.
Defensively, he's good but probably won’t be able to guard NBA point guards, because he already suffers when a quicker opponent takes him off the dribble. His defense on pick & rolls could use some improvement as well.
Although he generally puts in a good effort, sometimes he seems to lose a bit of focus, either committing foolish fouls, trying a spectacular pass over a simple one, or being a little late rotating on defense. However, these things are not uncommon for a 20 year old player competing with grown men in one of the most competitive leagues in the world outside the NBA.
