When NBA front offices make transactions, signing free agents and moving players via trade, team chemistry is not necessarily a focus.
The San Antonio Spurs' acquisition of sharpshooter Marco Belinelli was not headline news like Dwight Howard's decision to sign with the Houston Rockets. But as it turns out, Belinelli has been a perfect fit with the Spurs because of what he adds to the team.
Once considered one-dimensional, Belinelli has become a better all-around player under the tutelage of mastermind head coach Gregg Popovich. Plus, the seventh-year pro is not being called upon to help lead the scoring like he has been asked to do during his career.
Ultimately, Belinelli has seamlessly fit into the Spurs rotation and is helping San Antonio remain as an elite franchise in the Western Conference.
Shooting Has Improved Dramatically
According to John Schuhmann on the NBA Hang Time Blog, Belinelli is the most improved shooter in the entire NBA.
Well, that'll do.
Last season, Belinelli had an effective field-goal percentage of 46 percent on 610 attempts. Currently, Belinelli boasts an eFG% of 63.6—a 17.6 percent increase.
Belinelli's most noticeable improvement is his three-point shooting, raising his percentage from just a 35.7 percent mark to a league-leading 56.6 clip.
What will Marco Belinelli's final three-point percentage be?
The best single-season mark from deep in NBA history is 53.6 percent, accomplished by Kyle Korver in 2009-10. Now, let's not get carried away and hand Belinelli the record, but he has put together a rather impressive start.
As of Dec. 11, Belinelli is one of only three qualified players who have made at least 50 percent of their respective long-distance attempts. Though he does not shoot as often as the other two—Korver and Ryan Anderson of the New Orleans Pelicans—Belinelli is knocking down triples at an elite efficiency.
Overall, the Italian has made 52.9 percent of all attempts compared to just 39.5 last season.
And Belinelli's shooting improvement has much to do with his fellow teammates.
Perfect Complement in the Bench Rotation
Coming off the bench, Belinelli has typically found himself playing alongside the upstart Patty Mills and resurgent pair of Manu Ginobili and Boris Diaw.
As seen in the lineup stats on 82games.com, the group consisting of the four aforementioned players plus Jeff Ayres is scoring 1.39 points per possession compared to allowing 1.11.
Ball movement is key to this unit making baskets, and Belinelli is taking advantage of San Antonio's pick-and-roll offense, occupying vacated positions and creating open shots. Last season, Belinelli was assisted on 645 of 829 (77.8 percent) of his made shots (h/t Basketball-Reference).
Guess what? The Spurs have been pretty good at passing the ball lately.
Last year, San Antonio led the league in assists per game and is currently pacing the pack this season too.
As noted by Schuhmann, Ginobili has assisted Belinelli on 22 of 74 (29.7 percent) made shots, including this absolute dime from the Argentine. Additionally, Mills has accounted for 11 more (14.9 percent), so Belinelli has already meshed with his new backcourt teammates.
The Spurs second unit is working fantastically well together on both ends of the floor, and Belinelli is receiving his favorite shot—open spot-up jumpers—because of it.
Belinelli Has Overcome Being a Defensive Liability
Belinelli has never been accused of being an elite defender, and that won't start right now either.
Holding a career defensive rating of 110 (which is not good, by the way), Belinelli was a commodity only because of his offensive prowess. Otherwise, he could definitely be replaced.
This season, however, Belinelli's biggest shortcoming has been hidden by his teammates. According to NBA.com, the Spurs' team defensive rating with Belinelli on the floor is 96.1 (which is pretty good).
The San Antonio defense is ever-so-slightly more efficient (94.7 rating) when Belinelli is on the bench, but that is such a tedious difference because of his offense. Belinelli is an important reason why the Spurs have a 112.5 offensive rating with him compared to 101.5 without.
Individually, Belinelli has continued to make strides defensively, but it's the collective effort by San Antonio that has helped made him a perfect fit.
It's the kind of perfect fit that helps a team make a deep playoff run, something the Spurs are fully capable of doing once again.
